Why give up, ever?
If someone has to walk across the room to grab the device with the
root filesystem, then has to answer the phone, then deal with the
next interruption ... for an hour before getting back to the machine
they rebooted, why shouldn't it just work to plug in the USB flash
drive (CF card, MMC card, or whatever) *THEN* instead of having had
to rush and meet some arbitrarily early deadline?
When there's no root, I don't see how waiting for it to arrive
could be a lose...
