Knoppix changed my HOSTNAME env var?

[kclawson]

Knoppix newbie and only about 6 months on Linux. I ran it on a computer that already has Red Hat 9 installed. When I was done playing I shutdown. After booting Red Hat from hard disk, I noticed that the console prompt shows user@knoppix currdir$. The PS1 var looks normal ([\u@\h \W]\$). The /etc/hosts file looks good listing "localhost.localdomain". The /ect/sysconfig/network has "HOSTNAME=localhost.localdomain". The /etc/profile is calling /bin/hostname to set the HOSTNAME variable. I can reset the variable temporarily or hard code it in the /etc/profile I guess to make it permanant, but I can't really figure out what is going on. Running "hostname" replies "knoppix" after each boot and trying to reset the variable with "hostname" does not survive a reboot. I have even done a recursive grep of /etc for 'knoppix' and can't find anything. Also, this or some other issue has broken an NFS mount that worked perfectly before I played with Knoppix on this machine.

Anybody know what is going on?

I saw a Bugzilla report (#309) with the following: DHCP client should not try to push hostname. Could this have something to do with it?

Upon further review, this issue is clearly related to issue 304 in the Buzilla system. Knoppix DHCP client pushes the hostname up to the DNS server.
