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
