Interesting. I've downloaded the VM Image and tried to understand the
setup. Apparently there exist sort of two root trees / and /sysroot in
the system with some links targeting the /sysroot tree. What I'm
wondering about is that /dev/mapper/fedora-root is mounted several times
on /, /var, /usr and /sysroot (twice!) sometimes rw and sometimes ro.
The impression I get is that /sysroot is the actual root fs in the image
and / the ostree directory at least that's what the links seem to
suggest. I still don't understand the mount-voodoo though. Is there some
documentation about this available?
