kern/54383: NFS root configuration without dynamic protocols: dhcp, bootp, etc ...

[Steve Shorter]

Howdy!


	I only boot from Intel cards that support PXE.

	This greatly simplifies the administration
of large numbers of diskless machines. It makes kernel
changes trivial. If your going to go diskless you may
as well go all the way for the base/root system and kernel.

	If you need RAID disks for data then you can
throw some swap on them, but otherwise with memory
cheap you can usually get away without swap.

	The problem with hardrives isn't cost. Its a
source of failure and administrative overhead.
Avoid them. If you can't, then use RAID for data and
still PXE boot over the network.

	Upgrading kernel on each machine is a major drag
if there are lots of machines.

	In general a solution that is not scalable
is not a good one.
