Configuring a valid system hostname during install and boot

Registered by Robbie Williamson on 2010-10-19

We do not do a very good job of making sure that systems have a valid hostname. This session is to 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.

See the following thread for more detail:
