Hiya, running fedora 32 with your copr enabled and getting this from systemctl status lxcfs.service

rolled back to fedora 32 provided 4.0.1 and it starts up fine, as did previous lxc4 copr build

I can reproduce the error also on Fedora 31. lxcfs fails to start with:

Jul 05 23:08:14 host.example.com systemd[1]: Started FUSE filesystem for LXC.
Jul 05 23:08:14 host.example.com lxcfs[184173]: /usr/lib64/lxcfs/liblxcfs.so: undefined symbol: lxcfs_clone - Failed to open liblxcfs.so
Jul 05 23:08:14 host.example.com systemd[1]: lxcfs.service: Main process exited, code=exited, status=1/FAILURE

Not exactly sure what's going on here. Will investigate...

Created upstream issue lxc/lxcfs#420

[brauner]

Sent a fix for this just now.

[ganto]

I just released lxcfs-4.0.4-0.2 with the upstream fix included. Now I cannot reproduce the issue any more.

Excellent, thank you!

Loads up fine now :)
