Yes, thank you.

Unfortunately I find that if I ever use the GUI tool 
(system-config-network) to configure network than the '$' there gets 
automatically escaped on save ! :)

The back tick form of shell command substitution is preserved though, so 
I can write:
	DHCP_HOSTNAME=`hostname -s`

For some strange reasone, when I do that, I get 'host name lookup 
failure' during `service network restart´ invocation, so in the end I 
resorted to using just:
	DHCP_HOSTNAME=`hostname`
which seems to work properly until now, and now my router can see the 
computer names for its DHCP clients, which is a big step compared to 
seeing just the MAC address. :)

Thank you,
Timothy Madden
