That is my recommendation too! We prepared where we could, but there
were a number of things (setting the time being one) where we didn't
know we would like to do them until we were actually there. This was
made worse by the deployment running a build we weren't expecting.

And, at least on my ubuntu box, in date --help. I must say I have stared
at that man page in the past and never interpreted the
[MMDDhhmm[[CC]YY][.ss]] as instructions for setting the time, but now
you point it out, it is fairly obvious.

I did figure that there would be space issues.

The battery related commands were the ones that I was actually looking
for -- I didn't know you could set the time in OFW. A list of the
possible tests would have saved some time, I had to watch a few test
runs cycle through to the touch pad and keyboard tests before I could
investigate. That said, there is a workaround (run them all and wait) so
documentation for other things would be preferable if you have to choose
what to document.

I'm not really asking for improvements for any deadline, just making a
suggestion to help future ill-prepared travellers. An alternative would
be a way to copy the olpc and sugarlabs wikis -- I tried to do this in
Samoa (we made friends with the local ISP) but my time was limited and
my spider too naive, so I had to kill it.
