setting the client hostname

[Steve]

Can someone point me to where dhclient sets the hostname from what is received fron the dhcpd server? It appears to be some time after dhclient becomes a daemon which causes stdout and stderr to be closed and so I don't know how to debug this any further. Perhaps it is possible to write to the system log somehow?

My problem is that the hostname is set to one of two different values every other time the machine is booted. ie

boot #1 -> hostname A
boot #2 -> hostname B
boot #3 -> hostname A
boot #4 -> hostname B
etc

The hostname is always supposed to be A.
I'm trying to find out whay this is happening.

Thanks,
Steve
