If your linux installation has a non-trivial fstab, for instance separate /var or /var/log, I don't think a container would even boot because the devices /dev/sdXY are not there. So, you'll need to find a way to properly mount all necessary filesystems inside the container. I have never used nspawn, but the above is possible with LXC because one can write a container configuration file. If nspawn has a decent configuration syntax, then good... I also wouldn't make a habit of maintaining another linux distro like that especially if it is systemd-based. Systemd may not run smth if it detect a container virtualization.
