@adam:robins.wtfadamcstephensi'm gonna spend some time this morning on the wiki page12:11:07
@adam:robins.wtfadamcstephensi've also had people ask me how to build custom images, which i should really document :)12:14:29

@rungmc:matrix.orgrungmc I think you could justify an incus.simple option for folks who just want a basic testing or desktop installation or somesuch. Just spamming enter through the default options from incus admin init doesn't result in a preseed with anything system-specific and it's for sure the only way you could do default firewall rules. 17:00:37
@rungmc:matrix.orgrungmcHaving done plenty of stupid networking things, it's pretty trivial to go in and change all of that later if you want to do your own preseed. I'd be more worried about storage pools and some of the weirdness that can occur if you happen to be running some sort of DNS on the same box as Incus.17:01:58
@rungmc:matrix.orgrungmcType of idiot who would do the latter is probably not your target audience for that option, though 😜17:05:17
@adam:robins.wtfadamcstephens there's also incus admin init --minimal 17:12:05
@rungmc:matrix.orgrungmcWas that in LXD before the fork? I dunno how I missed that.17:36:27
@adam:robins.wtfadamcstephensyes17:36:32

@hexa:lossy.networkhexaok, probably have to look into zfs as the backing storage now as well08:37:31
@adam:robins.wtfadamcstephensi've zfs for years with incus/lxd, even moving between systems and pools. no problems i can remember12:48:04
@hexa:lossy.networkhexaso it does zfs send for stateful migration I assume?12:50:09
@hexa:lossy.networkhexaand ultimately an instance has its storage only backed by whatever raid constellation the local machine it currently resides on, correct?12:51:03
@adam:robins.wtfadamcstephensyeah i think it uses zfs send for a migration13:36:25
@adam:robins.wtfadamcstephensi've only tried that once or twice13:36:34
@adam:robins.wtfadamcstephensceph not working?13:36:48
@hexa:lossy.networkhexaso how does it catch up with changes to the zvol, since the guest is still running13:36:56
@hexa:lossy.networkhexaI can get it to work, I'm not sure I can reasonably get the colleagues to a point where they're in a position to maintain and debug it 🙂 13:37:32
@hexa:lossy.networkhexawe're primarily a network carrier13:37:52
@adam:robins.wtfadamcstephens
❯ incus move blank:just-bobcat bonk:
Error: Failed instance creation: Expected "criu" connection secret missing from migration sink target request
13:43:06
@adam:robins.wtfadamcstephenshmm13:43:07
@hexa:lossy.networkhexacontainer?13:45:01
@adam:robins.wtfadamcstephensno, it's a VM13:45:43
@hexa:lossy.networkhexahuh, so why CRIU13:46:13
@hexa:lossy.networkhexaor is that stateful migration with ZFS? 😄 13:46:35
@hexa:lossy.networkhexa * or is that a stateful migration with ZFS? 😄 13:46:39
@hexa:lossy.networkhexawhere it tries to freeze the VM13:46:47
@adam:robins.wtfadamcstephensyeah thats a stateful migration13:47:00
