@uep:matrix.org | yeah, I know. Bit of legacy issue there with too-small a real swap partition | 06:47:27 |
@uep:matrix.org | the zvol is lower priority and rarely gets hit | 06:47:58 |
@uep:matrix.org | (the pool and partitioning long pre-dates nixos, it was running ubuntu zfs for years) | 06:48:54 |
@uep:matrix.org | ok, very different timing on the laptop! | 06:50:06 |
@uep:matrix.org | no wait for settling, and 🎉 no wait now for the zvol swap to appear, so faster boot overall | 06:50:33 |
@elvishjerricco:matrix.org | well that's good at least :) | 06:50:52 |
@uep:matrix.org | that was actually the reason to try, I sort of expected it might help | 06:51:25 |
@elvishjerricco:matrix.org | in theory it should | 06:51:36 |
@elvishjerricco:matrix.org | in practice it seems a second or 3 slower on a lot of people's machines | 06:51:53 |
@uep:matrix.org | clearly depends on what's in the device tree. | 06:52:22 |
@uep:matrix.org | Nov 09 17:49:44 localhost systemd[1]: Finished Coldplug All udev Devices.
Nov 09 17:49:44 localhost systemd[1]: Starting Wait for udev To Complete Device Initialization...

@uep:matrix.org | (more messages in between of course, but the timing delay is not noticable on screen) | 06:55:02 |
@uep:matrix.org | In reply to @elvishjerricco:matrix.org the udev settle thing confused me, but then I remembered zfs pulls that in missed this before, there's even a note about it :)
Nov 09 17:49:44 localhost udevadm[132]: systemd-udev-settle.service is deprecated. Please fix zfs-import-rpool.service not to pull it in.

@elvishjerricco:matrix.org | yep. There's even a github issue about it: https://github.com/openzfs/zfs/issues/10891 | 07:01:00 |
@uep:matrix.org | comments in there refer to what we discussed as "incremental assembly" | 07:08:10 |
@uep:matrix.org | which is a reasonable name | 07:08:15 |
@uep:matrix.org | anyway, at least when it appears we can just use it via systemd | 07:20:01 |
