} I've got to ask, if you're in an NFS environment, why boot from flash at
} all?  Why not PXE boot or use etherboot?

I'm attempting to minimize reboot cycle time, since part of the test
suite involves 50 reboots per card, and with 5 cards in the system,
a minute extra boot time is suddenly four hours.

But I'll admit to not having gathered the data on that one, so I'll
give it a closer look.  If I PXE or etherboot, how would the kernel
environment get populated then?
