From the very beginning, how to initialize the CF flash, do it manually?
Or if the CF FS crashed, how do you roll it back?

The reason for put filo in etherboot.
- It can let boot from HD or net according to CMOS setting.
- Etherboot can produce zelf. We may got more space to put other stuff

as USB support... 3. Etherboot structure and support...
I may check if filo.zlef only include FILO ..., even it is not, we still
can
make it clean.
You have the same blind spot as Eric. For many people, boot over net is irrelevant. Why do they need to live with the overhead of network protocol stack and driver if all they want to to boot form some mass storage device ?

This is the bootstrap question.
LNXI booted etherboot to load our flashes up. Once it was up, I reflashed flash and CF with a FILO-only image.

We've never had it happen here, in several thousand nodes * several years. I'm sure it would not be fun.
But recall that many installations do not have ethernet connection of any kind, so there is no real recovery via ethernet in those cases. Ethernet-free machines constitute several thousand machines here at LANL.
We are in fact disconnecting gigE from about 1200 nodes as I speak.

How does the CF in your PDA get inited ? How do you recover your PDA when it crashed? Connect to the internet ?
How about your vacuum ? your refigurator, your microwave ?

Mount the CF in an other computer and put what you need on it.
There are a number of other ways.

We build appliances. They mount their FS read-only so that every time they boot the same way.
...embedded appliances are not the same as workstations or HPC's.
