It might also be useful to start lxcfs with debugging (`-d`) if there's nothing being logged about populating /proc/cpuinfo. This maybe?

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. > I can probably grant you privileges on abel as soon as I get an ack > from my fellow DSA mates. 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.
