Hmm. I thought he was suggesting that you use sed or something to
edit the 0.0.0.0 to the correct value at runtime. I didn't know
0.0.0.0 would be acceptable, and I've found that hostname "hacks", if
this is one, can fail from version to version of the kernel/resolver.
Specifically, some programs can be very particular about entries in
/etc/hosts; sendmail, rlogind, and lprng come to mind. I've had
trouble at one time or another with each of these as a result of
dynamic-ip's and/or masquerading.
I haven't taken the time to make sure I've gotten everything exactly
right -- I've just tended to to fix the problems as they crop up.
