Could you try this again, but without the trailing slash?
The goal is to check if /tmp is itself a symlink; with the
trailing slash, this looks at the pointed-to directory,
which is not what we want.  i.e. "ls -ld /tmp".

This is just showing that ~ and /tmp are on separate filesystems--
it's not saying anything about tmpfs directly; it could just be
that /home is a separate mount from /.

Run "stat" on / and /tmp and this will tell you if they are
different (look at the Device numbers).

Possibly.  systemd does not use any of the initscripts logic to
mount filesystems; I'm not even sure it respects RAMTMP--it
might not even look at it.
