Package request for incus-s6 package

Incus is a fork of lxd, with broader community support and engagement.

I expect the service files would be nearly identical to these:

Spoiler (click to show/hide)

I'm drafting what the execline file might look like, and here's what I've been testing in the command line

Code: [Select]

$ sudo incusd --group=incus --syslog
ERROR  [2025-06-14T22:17:02-06:00] Unable to parse system idmap                  err="No map found for user"

This message is particularly concerning

Code: [Select]

vhost_vsock kernel module not loaded

Here's a bit of a commented debug session.

Code: [Select]

$ # First I'll show what my current kernel is.
$ uname -a
Linux metroplex 6.14.9-artix1-1 #1 SMP PREEMPT_DYNAMIC Fri, 30 May 2025 19:25:06 +0000 x86_64 GNU/Linux
$ # Next, I list to see which modules are available
$ find /lib/modules -name "*vhost_vsock*"
/lib/modules/6.15.2-artix1-1/kernel/drivers/vhost/vhost_vsock.ko.zst
/lib/modules/6.12.32-1-lts/kernel/drivers/vhost/vhost_vsock.ko.zst
$ # Given this information, I'd bet a modprobe will work.

Each of

Code: [Select]

sudo modprobe vhost_vsock

Code: [Select]

sudo modprobe kernel/drivers/vhost/vhost_vsock

Code: [Select]

sudo modprobe kernel/drivers/vhost/vhost_vsock.ko.zst

all had

Code: [Select]

FATAL: module <the path> not found in directory /lib/modules/6.14.9-artix1-1

EDIT: the kernel module isn't loading bc my kernel modules aren't present. Known recurring issue on my system, not related to this.

Code: [Select]

$ sudo incusd --group=incus --syslog
ERROR  [2025-06-15T09:41:12-06:00] Unable to parse system idmap                  err="No map found for user"

If I check /etc/subuid and /etc/subgid, root is not listed. It's required for incus or LXD, apparently. Adding a known-to-work root mapping seems to have fixed the problem (though I'm unsure why the user wasn't present in the first place).

Code: [Select]

$ sudo incusd --group=incus --syslog
WARNING[2025-06-15T09:50:26-06:00] AppArmor support has been disabled because of lack of kernel support

When the above was running, the command sudo incus admin init worked, as did a few other commands like sudo incus top

This might not be all of the services desired, however. On my OpenRC Macaroni OS (Funtoo (Gentoo derivative) derivative) system, these are available:

Code: [Select]

$ rc-service --list | grep -E "(lxc|incus)"
incus
incus-lxcfs
incus-user
lxc
lxcfs

Here's an execline script that's been working so far:

Code: [Select]

#!/bin/execlineb -P
fdmove -c 2 1
exec incusd --group=incus --syslog
# vi: ft=execline
