As I understand it, ltsp uses dhcp in part to make IP address
assignments completely automatic. Infinite leases break this by
preventing address recycling.
As long as the dhcp server stays up, the only downside to lease
expirations is a few UDP packets between the workstation and the server
at lease renewal. Most of the time, a given workstation will get the
same address every time.
In a production environment, there are many justifications for leaving
your servers up all the time and few for leaving them down most of the
time.
Jim and the other developers have done an amazing job of making LTSP
ready to run "right out of the box". In any installation, however,
there will be aspects of *any* system that will require some
configuration. A checklist of likely problem points would be a great
idea, but I don't think infinite leases are a good idea in most
installations.
