THis is the weirdest part. All commands were run in order.

So I am all confused. But to prove that /tmp _is_ on tmpfs, here it is:

rrs at champaran:~$ ln x.sh /tmp/
ln: failed to create hard link `/tmp/x.sh' => `x.sh': Invalid
cross-device link


Would systemd have anything to do with this? I am running systemd.
