Description Coelacanthus 2023-08-11 15:31:53 UTC 
After update kernel to 6.4.x, we found sudo, groupmod, groupadd, usermod, useradd don't work in systemd-nspawn like this:

$ sudo ls
sudo: PAM account management error: Function not implemented

After checked, we found seccomp return wrong errno for netlink syscall. systemd-nspawn set it to EAFNOSUPPORT, but it return ENOSYS.
It can be fixed by this patch.
