I don't like to repeat myself, but ``Hostname is set by /etc/sysconfig,
/etc/sysconfig is sourced by /etc/rc''.  I know all about sub shell vs
sourced file and the effects on variables.  I have been writting /etc/rc
files for 15 years.

Just where are you setting $hostname at?  If your not doing it at about
line 61 of /etc/sysconfig your not doing it the right way!!!

You will note that at line 75 of /etc/rc the file /etc/sysconf is sourced
into /etc/rc which means $hostname is defined.

You will also note that this is the same way that /etc/netstart now
gets this value from /etc/sysconfig.
