[techtalk] Debian system host name

[Judith Elaine Bush]

I'm changing the host name on my debian potato box (since dynamic dns
died at justlinux.com -- i've gone with zoneedit.com). 

When I last set up the box, I just answered an installation question
about the host name. Does Debian have a simple hostname update script?

I'm grepping through /etc/* and /etc/*/* to find instances to change
by hand -- but Debian often has a better way than by hand....

Thanks,
