because it's what I use all the time, and that may well NOT be what's used
by Openbox.  It obviously uses a shell of some sort, but which one is open

Extra thanks to William, who did indeed spot the problem: I was using a
bash construct while openbox was using some more stripped down sh.
Changing the line to

if [ "$(cat /etc/hostname)" = "crom" ]

(ie. with "=" instead of "==") has fixed the problem.
