  I did try to reproduce the issue over the weekend with qemu. Using
qemu-user-static and systemd-nspawn was insufficient due to lxcfs
needing proper access to the fuse kernel api. After trying and failing
to bootstrap an armhf instance by hand, I grabbed a raspberry pi 2
bookworm image from raspi.d.n, and got it running under qemu-system-
arm. Within that environment, lxcfs appeared to work correctly
(/var/lib/lxcfs/proc/cpuinfo was correct, no obvious errors or warnings
noticed). I didn't spin up a full lxc container instance within that
environment.

  If it's possible to get temporary permissions on abel, that would be
useful.

  One other thing to double check on ci-worker-armhf-01 would be the
contents of /var/lib/lxcfs/proc/cpuinfo, so we can see what lxcfs is
doing from the host side.
