The only thing I transferred that was unusual is hard links.  Otherwise
it was just
rsync --progress -avhH --numeric-ids followed by the various source
directories root file system to a subvolume rootfs, /usr to a subvolume
called usr, var to a subvolume called var and home to  a subvolume
called home.  And what is more confusing, I did check the contents of
postgresql.conf and they matched exactly, the one on my ext4 system and
the one on the btrfs file system -- so I don't know why the check
program gave that message.  Also, another thing which was not consistent
is that in my first boot mysql service did not start, but it did in
subsequent boots.  Now, I did not transfer anything under /var/run as
its linked to /run, same for /var/lock as its linked to /run/lock.
Device files, I did not transfer anythin specific, I would think udev
would create those under /dev.  In this case, I wish I were doing
something dumb, it would not be fun, but  at least I could proceed and I
could run with the system.
