[Voyage-linux] Using a 'standard' voyage image on many remote boxes

[Rasjid Wilcox]

Hi.

I have been testing Voyage Linux on a WRAP box, and am very pleased
with the results.

In the medium term there will be around 40 boxes in the field, and in
general they will only be accessible remotely.  The number could grow
to 80 or more over time.

I am trying to think of ways that one could have a 'standard' image
that can be easily applied to all boxes, and updated remotely.

My thoughts so far are as follow:
a) partition the CF into 3 partitions.  Voyage is in the first
partition, the second partition is a config partition (2MB size say),
and the third is a small (32MB or less) 'upgrade' partition that
contains a smaller version of Linux (possibly a cut down version of
Voyage, or perhaps LEAF Bering uClibc).
b) to perform a remote 'reflash' of voyage, tell lilo to boot to the
3rd partition, reboot, log in again remotely and upload and rewrite
the first (voyage) partition, rerun lilo and reboot to voyage

I have not tested any of this yet.

Is there another way of achieving my goal?  Is the approach above
doomed to failure?

If anyone has any thoughts I'd love to hear about them.  Otherwise,
I'll report my success or failure.

Cheers,

Rasjid.
