I haven't measured _compression_ time, which might be relevant for host-side initrd generation. and it might make tools unhappy? 16:43:30 <bgilbert> lucab: right 16:43:49 <bgilbert> i.e. any initrd inspection tools that don't support zstd 16:44:13 <bgilbert> note that this is with -19, which is not the dracut default if you ask for --zstd; dracut defaults to -15 16:45:01 <bgilbert> one other thing: before we can switch our initrd, coreos-installer must be updated to support zstd or `pxe customize` will break. I have a working draft PR, which will need to make it into a release 16:45:05 <bgilbert> the PR isn't trivial unfortunately 16:45:37 <lucab> (trivial PRs are boring to review!) 16:45:42 <bgilbert> lucab: :-) 16:45:57 <dustymabe> send me your trivial PRs, send the non-trivial ones to lucab 16:46:01 <bgilbert> hah 16:46:04 <bgilbert> :-P 16:46:22 <jlebon> note also that the el8 kernel doesn't support zstd initrds, so this would be an FCOS-only thing 16:46:30 <jlebon> el9 does 16:46:31 <bgilbert> FCOS and el9, yeah 16:47:20 <jlebon> dustymabe: are you suggesting trying to drive this as a Fedora change? 16:47:30 <travier> I can not find a change for Fedora in general but this would be a good change to push to all variants 16:47:36 <lucab> ah, I was just looking for that, bummer 16:47:57 <dustymabe> jlebon: i'm not suggesting we block on that, but I do like to diverge from the other variants as little as possible 16:48:06 <jlebon> dustymabe: +1 16:48:09 <dustymabe> i.e. we can push this change but followup and try to get other variants to consider it 16:48:17 <bgilbert> given where we are in the change process, it'd be an F38 thing I think 16:48:23 <dustymabe> bgilbert: correct 16:48:33 <bgilbert> so we could include the FCOS experience as a PoC 16:48:35 <dustymabe> eventual consistency 16:48:41 <dustymabe> :) 16:49:02 <bgilbert> #proposed We will add the zstd package to FCOS, and switch our initrd to use it. 16:49:06 <travier> zstd is already used a lot in Fedora elsewhere now so that should not be controversial (famou last words) 16:49:11 <travier> famous* 16:49:17 <travier> +1 16:49:23 <travier> for the proposal 16:49:31 <dustymabe> +1 16:49:33 <jmarrero> +1 16:49:39 <jlebon> ack 16:50:05 * dustymabe kind of wishes we could switch our image artifacts to be compressed with zstd too 16:50:34 <bgilbert> #agreed We will add the zstd package to FCOS, and switch our initrd to use it. 16:50:39 <bgilbert> cool, thanks all 16:50:47 <miabbott> there's a thread on devel about using zstd to compress modules + mentions initrd in passing - https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/YYSL4WQ6A337UNAR3AYBWKAROJ42SBOO/#KFIAXNVCODGO2ODOZ53OM5MB3PWUQ3TY 16:50:51 <lucab> bgilbert: does libzstd bump its soname often? 16:51:15 <bgilbert> lucab: oh, hmm 16:51:24 <miabbott> (pretty old thread, though) 16:51:25 <bgilbert> looks like it's on 1 right now, but I haven't checked the policy 16:51:46 <lucab> (just asking, for coreos-installer) 16:51:57 <bgilbert> right 16:52:01 <jlebon> dustymabe: my understanding is xz still has better compression ratio 16:52:17 <jlebon> ok cool, ready to move on? 16:52:28 <bgilbert> it's also 1 in RHEL 8 16:52:28 <dustymabe> +1 16:52:40 <bgilbert> lucab: we don't ship separate coreos-installer binaries, unlike Ignition and Butane 16:52:55 <jlebon> #topic extend grub boot prompt timeout on platforms with full console access 16:52:58 <jlebon> #link https://github.com/coreos/fedora-coreos-tracker/issues/1236 16:52:59 <bgilbert> except for mirror.openshift.com, which arguably only has to run on RHEL (though we'll have two relevant RHEL majors) 16:53:05 <jlebon> looks like this one has had the meeting label for a while 16:53:10 <jlebon> dustymabe: want to take that one? 16:53:21 <dustymabe> ahh yes 16:53:48 <lucab> bgilbert: that's a good situation then I think wrt dynamic loading 16:53:58 <bgilbert> lucab: +1 16:54:00 <dustymabe> I think here I'm arguing to extend the grub timeout on platforms where console access is reasonable to something more than 1s 16:54:37 <dustymabe> on platforms where we can't have console access (for whatever reason) we leave it alone or possibly make it 0 there 16:55:30 <dustymabe> in the ticket bgilbert makes some good arguments for leaving it as is 16:55:47 <dustymabe> I'm OK with either outcome, just wanted to start the discussion 16:56:51 <jlebon> concretely which platforms would this affect then? 16:58:02 <dustymabe> any platform where console access is possible 16:58:19 <dustymabe> well - I should say 2 way console access (read/write) 16:58:38 <dustymabe> previously we could discount AWS here, but they recently added read/write serial console support (which has been amazing) 16:58:53 <jlebon> oh sweet, didn't know that 16:59:06 <dustymabe> We'd have to look at the others to see what the limitations of each are 16:59:22 * dustymabe doesn't have that knowledge readily available 16:59:29 <jlebon> yeah, i'm still wary of adding e.g. 4 seconds of boot time on every boot to multiple platforms 16:59:40 <jlebon> have we had users report this as a legitimate UX issue? 16:59:49 <dustymabe> correct, I'm just advocating for "more than 1s" 16:59:59 <dustymabe> doesn't have to jump to 5 17:00:06 <dustymabe> even 2 is twice as much time as we have today 17:00:11 <jlebon> haha 17:01:03 <bgilbert> to summarize my arguments against: boot happens frequently (at least every OS release) and debugging happens approximately never. 17:01:12 <bgilbert> the countdown can be stopped by pressing literally any key, so the user doesn't really need to know what they're doing 17:02:03 <bgilbert> in cases where the boot menu is going by too fast, even 5 seconds won't help much: 20-minute BIOS POSTs and clouds that are slow to start a remote console 17:02:24 <jlebon> we can also add documentation about this in the troubleshooting section 17:02:25 <bgilbert> and we have debugging docs that can explain how to interrupt the boot 17:02:28 <bgilbert> yup 17:02:34 <dustymabe> the "any key" part is important information - but still the user might not necessarily know that (I didn't until recently) 17:02:47 <dustymabe> yeah docs help here 17:03:36 <dustymabe> another hypothetical situation: keyboard doesn't initialize fast enough 17:04:27 <dustymabe> I've definitely hit sitatuions like that on my Rpi (or at least I think that was the problem) 17:04:28 <bgilbert> dustymabe: hmm, haven't seen that case 17:05:09 <dustymabe> either way. I think I've talked enough. Will let others discuss 17:05:11 <jlebon> to repeat my earlier question, has any user (other than dustymabe) reported this as an issue in the past? 17:05:40 <bgilbert> possibly relevant: I just tested timeout=0 in qemu and haven't been able to get to a menu at all 17:06:10 <dustymabe> at least one thinks its useful :) 17:06:28 <dustymabe> this was a slightly different problem: https://github.com/coreos/fedora-coreos-config/pull/281 17:06:42 <lucab> dustymabe: are you mostly concerned with first-boot debugging, or any boot in general? 17:06:42 <dustymabe> i.e. the Live ISO - not the FCOS disk image 17:07:05 <dustymabe> lucab: any boot - any time I need to catch grub (for whatever reason) 17:07:19 <dustymabe> maybe my system hangs on boot after upgrade and I need to select the rollback kernel entry 17:07:23 <jlebon> i think that live ISO PR predates iso kargs 17:08:30 <dustymabe> if you've ever had a system with a long reboot/POST cycle, you know how frustrating it is to miss the GRUB prompt 17:08:35 <bgilbert> jlebon: yeah 17:09:54 <dustymabe> also, just holding down a key the whole time isn't great.. what if your previous menus (BIOS/UEFI) have special keys too? you have to make sure you're using one that doesn't affect them 17:10:00 <bgilbert> "boot takes too long so let's make it longer" is an argument :-D 17:10:13 <dustymabe> :) 17:10:47 <dustymabe> I think I'm not being very convincing - and that is OK :) - we probably shouldn't waste too much time here, though 17:12:07 <jlebon> yeah, tricky... i'm not sure where to go from here. should we keep discussing this in the ticket? 17:12:45 <dustymabe> nah. I think we can close it out 17:12:46 <jlebon> i think this would be more convincing if multiple people felt frustrated by the short timeout 17:12:49 <bgilbert> IMO we should close it out. we can always revisit if a need arises, but I concur that there doesn't seem to be much demand for this right now 17:12:52 <bgilbert> yup 17:13:11 <lucab> I won't be much opposed to a 1s -> 2s change, but at the same time I'd be doubtful about any real advantage of doing that 17:13:28 <jlebon> ok, let's move on. thanks for bringing this up dustymabe! 17:13:36 <dustymabe> jlebon: can you #info or something? 17:14:34 <jlebon> #info there seems to be insufficient demand for a longer timeout. we will not pursue this for now but may reconsider in the future pending more convincing feedback. 17:14:42 <jlebon> does that work? 17:14:59 <walters> if it's any `console`ation I'm sure we'll be talking about this again 17:15:19 <dustymabe> WFM 17:15:28 <dustymabe> maybe s/demand/desire/ 17:15:37 <jlebon> #undo 17:15:37 <zodbot> Removing item from minutes: INFO by jlebon at 17:14:34 : there seems to be insufficient demand for a longer timeout. we will not pursue this for now but may reconsider in the future pending more convincing feedback. 17:15:42 <jlebon> #info there seems to be insufficient desire for a longer timeout. we will not pursue this for now but may reconsider in the future pending more convincing feedback. 17:15:58 <jlebon> ok cool 17:16:02 <jlebon> #topic Change default to be equivalent of quiet 17:16:05 <jlebon> #link https://github.com/coreos/fedora-coreos-tracker/issues/1244 17:16:15 <jlebon> walters: want to take this one? 17:16:30 <walters> ok 17:16:46 <jlebon> +1 17:16:48 <jlebon> #chair walters 17:16:48 <zodbot> Current chairs: bgilbert dustymabe jbrooks jlebon jmarrero lucab miabbott ravanelli saqali travier walters 17:16:54 <walters> So...a lot of history here but basically our console is very verbose compared to the Anaconda default which injects `quiet` 17:17:18 <walters> this verbosity in turn triggers surprising problems: https://lwn.net/Articles/800946/ 17:17:30 <walters> it can cause soft or even hard kernel lockups 17:17:42 <walters> we're moving to drop use of the serial console 17:18:03 <walters> but...even for people that do want the serial console, I don't think defaulting to debug level is useful 17:18:13 <walters> now as I say, I think really we should change the Fedora global kernel default 17:18:14 <bgilbert> we default to info, not debug 17:18:18 <lucab> (we absolutely had users hitting those hard lockups due to console, on both RHCOS and FCOS) 17:18:32 <walters> but basically we can lead the way on this to start 17:20:24 <walters> otoh, I think I'd be OK trying to push to change the kernel to start, it's possible that this just hasn't come up 17:20:43 <bgilbert> the existing log level does present a usability problem for console logins 17:21:02 <jlebon> makes sense to me! this and zstd, we should make sure we follow-up on the Fedora change if we want to lead 17:21:36 <jlebon> if anaconda defaults quiet anyway, this would just be lowering the default further down in the stack 17:22:29 <jlebon> so hopefully shouldn't be controversial... 17:22:36 <jlebon> famous last words 17:22:47 <walters> I'm assuming everyone agrees that we *do* want console output of some form, i.e. we're not going to inject `quiet` 17:23:38 <jlebon> ahh right. quiet affects more than just printk level 17:23:57 <dustymabe> quiet also affects the boot, which is where we might want more info 17:23:58 <lucab> what does `quiet` translates to, internally in the kernel? 17:24:37 * jlebon runs quiet in a `cosa run -c` 17:24:50 <jlebon> it also silences systemd 17:24:57 <jlebon> and affects both the initrd and real root 17:25:03 <walters> lucab: https://github.com/torvalds/linux/blob/master/init/main.c#L242 17:25:16 <jlebon> whereas here we're talking about just the real root, and just printk 17:25:50 <dustymabe> right - so change the kernel compile flag, as colin mentioned earlier isn't necessarily what we want either 17:26:12 <dustymabe> right? 17:26:26 <walters> yeah good point; changing the kernel default does mean we'd want to analyze the diff before the initramfs 17:26:46 <walters> hmm actually, i think it'd suppress most if not all messages actually 17:27:37 <dustymabe> could we just deliver this as suggested by lucab as a sysctl dropin in the real root and maybe look at doing this fedora wide (maybe in some fedora-release package, or maybe the kernel)? 17:28:03 <dustymabe> obviously anaconda based installs already have `quiet` so it won't really affect them 17:28:20 <walters> agree sysctl is cleaner *except* we then can't (afaik) easily do the logic for "only go quieter, not more verbose" 17:28:23 <bgilbert> for editions that use `quiet`, wouldn't that stop people from removing `quiet` and getting verbosity? 17:28:27 <bgilbert> right 17:29:21 <dustymabe> yes, there would be two layers then 17:29:38 <dustymabe> not for us, but for others 17:29:58 <dustymabe> in that case let's just ship the sysctl.d dropin for us only (we don't have anaconda/quiet)? 17:30:10 <dustymabe> or is there still a problem with that? 17:30:14 <lucab> we can have different sysctl in initramfs and rootfs by the way I think, for us 17:30:33 <dustymabe> lucab: right (I assume they get applied at different times)? 17:30:59 <walters> dustymabe: we'd still break the ability to use `quiet` for us which I think would be surprising 17:31:15 <dustymabe> would we? 17:31:17 <bgilbert> walters: how so? `quiet` would just be redundant 17:31:23 <dustymabe> ^^ 17:31:24 <jlebon> walters: the API would be that users could override the file via Ignition 17:31:32 <bgilbert> we'd break the ability to remove `quiet`, but we already don't have it 17:31:36 <walters> if we use the sysctl, we'd override what they provide on the kernel cmdline 17:31:54 <dustymabe> i.e. if they provided debug? 17:32:15 <walters> well yes, actually if they provide `debug` *or* `quiet` on the kernel cmdline 17:32:36 <bgilbert> but the sysctl would be equivalent to `quiet`? 17:32:44 <bgilbert> re kernel log level 17:32:59 <dustymabe> yeah, but he's arguing we want to support going the other way too 17:33:17 <walters> the admin specifying `quiet` would apply to the initramfs too 17:33:49 <dustymabe> i'd just really like to not have a whole nother systemd service needed for this :( 17:34:01 <bgilbert> walters: I think you're arguing that the sysctl would somehow interfere with the actual `quiet` karg somehow? 17:34:11 <bgilbert> I agree it would interfere with `debug` 17:34:13 <walters> bgilbert: right; wouldn't it? 17:34:19 <bgilbert> I'm arguing it wouldn't 17:34:30 <bgilbert> because it sets the log level that `quiet` already sets 17:34:40 <walters> but only for the real root 17:34:56 <bgilbert> okay, so `quiet` sets the log level in the initrd, then we get to the real root and the sysctl is redundant 17:34:58 <jlebon> real root is a subset of the whole boot :) 17:35:11 <walters> no, `quiet` is parsed by the kernel 17:35:15 <walters> and it's parsed by systemd 17:35:20 <bgilbert> yes 17:35:30 <bgilbert> the sysctl is a strict subset of `quiet` 17:35:35 <walters> `quiet` is for desktop systems usually where we want to look pretty 17:35:55 <bgilbert> thus if the user manually specified `quiet`, it would do more things than the sysctl, but the sysctl wouldn't change anything back 17:36:07 <jlebon> the action the sysctl does is a subset of what quiet does 17:36:32 <walters> hmm ok I think you may be right; I may be getting mixed up on debug/info/warn 17:36:56 <lucab> (worst case, a systemd generator which spits the sysctl fragment if the cmdline has no other quiet/debug/etc) 17:37:10 <jlebon> but circling back re. debug, how much do we care about that? are we ok with users also having to override the sysctl? 17:37:11 <walters> this all said, the sysctl would break the use of `debug` (intending to apply that to the real root too) right? 17:37:16 <bgilbert> right 17:37:43 <dustymabe> right, quiet == OK, debug == still masked, need to delete sysctl dropin 17:38:12 <walters> i can easily imagine a kernel support engineer getting confused at a nonfunctional documented kernel API 17:38:22 <bgilbert> I don't see a trivial systemd service with ConditionKernelCommandLine as a huge problem; it doesn't need to sequentially order with anything 17:38:34 <bgilbert> for setting the sysctl 17:39:12 <walters> yeah; and I think hopefully we can argue to include this in e.g. dracut (or perhaps systemd wants to handle this) 17:40:08 <bgilbert> though lucab's generator has merit 17:40:26 <bgilbert> avoids Ignition configs having to disable a magic service name 17:40:54 <walters> Well, we can use `ConditionKernelCommandLine=!quiet` etc as micah suggested 17:40:55 <lucab> my reading of quiet/debug/etc semantic is "kernel loglevel up to the point where userland components can further tweak it" 17:40:57 <dustymabe> does sysctl support /run/ ? 17:41:10 <bgilbert> (or a service that's an injected dependency of systemd-sysctl) 17:41:31 <lucab> dustymabe: yes, https://www.freedesktop.org/software/systemd/man/sysctl.d.html 17:41:58 <bgilbert> walters: I mean if someone wants to disable the service without modifying kargs 17:41:59 <dustymabe> +1 17:42:22 <jlebon> in walters' PR, the systemd unit runs from the initrd, so it can't be overriden via Ignition, but users are still free to add a regular sysctl dropin via Ignition 17:43:06 <bgilbert> hmm, initrd seems like an odd choice 17:43:19 <bgilbert> for something only affecting the real root 17:43:45 <lucab> agreed, generally speaking I'd be happy to push things out of initrd 17:44:08 <walters> yeah I agree having it in the real root seems simplest 17:44:28 <walters> I was just thinking "I want this at the end of the initrd" 17:44:39 <walters> but end of the initrd = "real root" 17:45:06 <bgilbert> I'm currently thinking a prereq service for systemd-sysctl makes the most sense 17:45:11 <jlebon> then the real root will awkwardly switch from info to silent a quarter of the way through 17:45:22 <bgilbert> hmm 17:45:33 <bgilbert> we probably don't need to work through implementation details here though 17:45:34 <jlebon> though right now the initrd also awkwardly switches, so meh 17:45:35 <bgilbert> we're already 15m over 17:45:39 <jlebon> yeah, agreed 17:45:56 <lucab> :) 17:46:08 <dustymabe> or.. we could do nothing :) 17:46:15 <bgilbert> also true 17:46:30 <bgilbert> or actually 17:46:36 <bgilbert> we could do the whole boot on info, and then switch after 17:46:49 <dustymabe> +1 17:46:51 <jlebon> do we want to draw any info/proposed here or just leave it upstream for now? 17:47:16 <jlebon> #info there's general agreement this would be good, but implementation details are still to be fleshed out 17:47:19 <jlebon> there :) 17:47:34 <jlebon> ok, will end this in 60s unless someone wants to add something 17:47:59 <jlebon> (i can do a 60s open floor if folks would like, but we're really over) 17:48:33 <jlebon> #endmeeting
