Subject: [PATCH] Adjust UUID lower-case translation from straight-forward
 tr(1) usage to an equivalent csh(1) usage as tr(1) stays in /usr/bin and
 /etc/rc.d/hostid has just the root filesystem (and this way mainly the tools
 in /bin) available.

I've chosen csh(1) here as the string manipulation tools available in
/bin is extremely limited and the (only) alternative ed(1) usage would
have been a lot more complicated or even might require a temporary file.
