[pkg-lxc-devel] Bug#1114596: Missing dependency on fuse3

[Stefano Rivera]

Package: lxcfs
Version: 6.0.4-1
Severity: serious

On an upgrade from bookworm (with bpo) to trixie, lxcfs failed to start, 
as fuse3 wasn't installed.

I noticed the missing fusermount, and installed fuse3. That fixed the 
issue. I see the systemd unit has
ExecStopPost=-/bin/fusermount -u /var/lib/lxcfs
which should mean that it *isn't* needed, but clearly something was...

So, I presume this is a missing dependency.
