| zyga | good morning | 07:51 |
| mborzecki | re | 07:55 |
| mborzecki | mvo: zyga: hey | 07:55 |
| zyga | :-) | 07:55 |
| zyga | mvo hey | 07:55 |
| mvo | good morning zyga and mborzecki ! | 07:55 |
| zyga | mvo I learned of a very useful feature of raspberry pi yesterday | 07:56 |
| zyga | mvo pi can be booted from USB (as in driven by USB connection entirely) without any SD cards | 07:56 |
| zyga | there are official tools and support for that | 07:56 |
| zyga | the configuration is quite flexible, allowing "override" from usb or fallback to regular boot | 07:57 |
| zyga | there's also some very useful thing you should look at at some point, allowing watchdog recovery during boot process that hanged | 07:57 |
| zyga | and the best thing is, it's just a toggle, very easy to set up, unrelated to anything on SD cards | 07:57 |
| zyga | I also had a look at the try boot mode | 07:58 |
| zyga | but I didn't run that yet | 07:58 |
| mvo | zyga: sounds super interssting, I would love to hvae the watchdog boot, I think that would be a great win | 07:58 |
| zyga | not sure if I will pick any of that up as a part of my work yet, as priority for pi is currently low, but I think it's fairly complete in terms of features for both testing and proper IOT operation | 07:59 |
| zyga | let me show you how to enable it | 07:59 |
| zyga | this is the try boot mode: https://github.com/raspberrypi/linux/commit/757666748ebf69dc161a262faa3717a14d68e5aa | 08:00 |
| zyga | it's an out of tree patch, as far as I know, it would needed to be applied to the ubuntu pi kernel | 08:00 |
| zyga | the boot selection and watchdog are described on https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md | 08:01 |
| zyga | the things to grep for are MAX_RESTARTS | 08:01 |
| mvo | zyga: yeah, dave told us about the tryboot, we plan to use this, ideally in close cooperation with dave | 08:01 |
| zyga | mvo, that's it so far, I'm off to learn yoto layering | 08:02 |
| zyga | mvo oh, I submitted zmk to fedora | 08:02 |
| zyga | opensuse is next | 08:02 |
| zyga | and then I can see if it would be possible to improve small bits of snapd makefiles with it | 08:03 |
| mvo | zyga: cool! thanks for the pointers, I check that out | 08:06 |
| zyga | mvo I also found POWER_OFF_ON_HALT interesting, it might be a good thing to expose via gadget | 08:06 |
| zyga | so if you have no hats, your pi can really shut down and stay off | 08:06 |
| zyga | and not just reboot like it does today | 08:06 |
| zyga | pstolowski good morning :) | 08:07 |
| pstolowski | heya | 08:07 |
| mborzecki | pstolowski: hey | 08:07 |
| pstolowski | mvo: hey, i've tagged https://github.com/snapcore/snapd/pull/9883 for 2.49, going to add a unit test to it | 08:18 |
| mup | PR #9883: cmd/snap-preseed: initialize snap.SanitizePlugsSlots for gadget in seeds <Bug> <Preseeding 🍞> <Created by stolowski> <https://github.com/snapcore/snapd/pull/9883> | 08:18 |
| mvo | pstolowski: thank you! | 08:24 |
| Fleck | hello, is there a way to get snapd working on old ubuntu 11.10? (Don't ask why not upgrade etc :D) | 09:13 |
| pstolowski | Fleck: no, due to systemd, apparmor & old kernel. 14.04 was the oldest that got snapd support, and that already was challenging | 10:00 |
| Fleck | ok, thank you pstolowski | 10:01 |
| ogra | there is https://help.ubuntu.com/community/EOLUpgrades to get you to a supported release though | 10:16 |
| mvo | mborzecki: fwiw, I replied to 9873 | 10:51 |
| mvo | mborzecki: tl;dr happy to change thing but it would not be symetrical to what we do with layOutStructureContent anymore | 10:51 |
| Fleck | ogra: yes, I know that, thanks! :) | 11:12 |
| mvo | ijohnson: hey, is it ok to squash-merge 9885 or would you rather keep the individual commits because they are "nicer" than lumbing them together? | 11:41 |
| ijohnson | hey mvo | 11:42 |
| ijohnson | let me take a look, I don't remember what 9885 is | 11:42 |
| mvo | ijohnson: no worries | 11:42 |
| mvo | ijohnson: also no rush | 11:42 |
| ijohnson | mvo: yeah it should be fine to squash merge them if you want to, but note that I didn't add any unit tests there yet, someone should do that before we merge I think | 11:42 |
| ijohnson | I meant to do that but didn't get time on Friday, I called this out in the SU doc, but I guess I forgot to explain that in the PR description | 11:43 |
| mvo | ijohnson: oh, ok | 11:43 |
| mvo | ijohnson: I add a note there | 11:44 |
| ijohnson | let me try and write some quickly since it doesn't appear that anyone else has pickedu p the mantle | 11:44 |
| mvo | ijohnson: thanks! no rush fwiw | 11:44 |
| mvo | pstolowski: is it ok to squash merge 9883? | 11:46 |
| pstolowski | mvo: yes! | 11:46 |
| mvo | ta | 11:46 |

| mvo | pedronis: nice! | 12:20 |
| om26er | How does UbuntuCore ensure that systemd is able to see installed snap packages' .mount unit files on boot ? | 12:34 |
| om26er | in our case we are seeing https://github.com/systemd/systemd/issues/8732 -- Does UbuntuCore incorporate some sort of "hack" for that ? | 12:34 |
| om26er | maybe ogra you know that ^ | 12:34 |
| om26er | I tried creating bind mounts for /etc/systemd/system on an external partition and systemd seems to always "miss" those units | 12:35 |
| ogra | no, there is no hack regarding systemd stuff on core | 12:36 |
| ogra | snapd just puts the files into /etc/systemd/system IIRC and relies on systemd to DTRT with them | 12:36 |
| ogra | and /etc/system i writable per /etc/system-image/writable-paths | 12:38 |
| ogra | s/i/is/ | 12:38 |
| ogra | err ... /etc/systemd indeed | 12:38 |
| om26er | for a "classic" system that is generally fine. For a system where rootfs is read-only we have to bind-mount /etc/systemd on a "writable" partition and when I actually do that, systemd seems to "miss" the .mount units all together | 12:39 |
| om26er | systemctl daemon-reload and systemctl start default.target seems to "fix" that but that's a hack really. | 12:40 |
| om26er | Anyways, it's good to know that UbuntuCore doesn't any such hacks, so I guess the issue is likely on my end | 12:40 |
| mvo | pedronis: I had a revert bits in 9873 again, sorry for that. the overlord tests fail and I think I can only add this in 9875 because before passing the kernelroot is not wired up yet in the higher layers :/ | 12:44 |
| mvo | pedronis: sorry for that, I only ran the local tests but not the overlord tests initially | 12:44 |
| pedronis | mvo: ok | 12:44 |
| mborzecki | om26er: well that's what ubuntu core does, /etc/systemd/system comes from a writable partition, as do a couple of other locations | 13:09 |
| mborzecki | om26er: this files defines relevant locations: https://github.com/snapcore/core20/blob/master/static/etc/system-image/writable-paths | 13:10 |
| om26er | mborzecki my fstab, inspired by the above link looks like https://gist.github.com/om26er/0a331e5cd20b81ecd81fc9bd85c39c69 -- However it seem there is a race condition somewhere. Sometimes systemd is not able to see the mount units of my snap packages, hence their mounting gets skipped, causing broken snaps | 13:15 |
| ijohnson | om26er: ubuntu core mounts the units before systemd starts frm the initrd, hence why it works w/o race conditions on ubuntu core | 13:16 |
| om26er | ijohnson ah, that would definitely explain it. | 13:17 |
| mborzecki | om26er: hmm otoh fstab generator runs early, afaict it should pick up those mounts and then they would get ordered before snaps? | 13:18 |
| om26er | I think Lennart's reply here https://github.com/systemd/systemd/issues/8732 also supports what ijohnson said. I was curious to know what exactly UbuntuCore is doing to circumvent that | 13:20 |
