This isn't strictly about performance, but about correctness.  I didn't see a 
better place, so I thought I'd try it in the category and see.

We do not do a very good job of making sure that systems have a valid 
hostname.  Many email related tools depend on having a valid hostname.  I see 
bugs all the time for Postfix and Amavisd-new (the most recent of which was 
today, thus I'm motivated to write this) that aren't package bugs, but invalid 
system hostname settings.  This has been going on long enough that there is a 
5 digit bug about the problem that's still open and our amavisd-new package 
has a patch specifically added to make it clearer how to work around this 

I'd like to see us review the ways that hostname gets set during install and 
on boot for desktop and server and for DHCP and static assignment and have 
clear documentation on how this is supposed to work so we can identify all the 
current deficiencies and get them fixed.
