No, all installations have been done from scratch using the standard installer, except for one which was an upgrade from 10.04. > > Regardless, it's not really supported to remove /etc/hostname.

Yeah I'm aware removing /etc/hostname isn't a good move. The story of how I ended up down this path is that in 10.04 you could set /etc/hostname to the magic string "(none)" and the DHCP supplied hostname would be honored. On my desktop the upgrade to 12.04 removed /etc/hostname (it had the magic string), and so I figured that was no longer supported. However the DHCP supplied hostname was still honored, though I had this login bug. There didn't seem to be another way to have the DHCP hostname honored. Having the DHCP hostname honored is convenient for us as it simplifies image deployment. Blat the image onto the desktop, stick it on the network, it picks up its hostname from DHCP and off we go, minimal intervention required. It's not a huge hassle to change /etc/hostname post image deployment, but it's something we didn't used to have to do.
