clean olpc-update needs reboot

[Chris Marshall]

In the process of updating 2 different G1G1 XOs from
8.2-760 to 8.2-762 this evening I made the following
observations:

1. one XO completed the 'olpc-update -r 8.2-760' command
    without a hitch

2. the other XO seemed to start ok but then there appeared
    a number of error messages with terms cafe, usb,... in them
    and the laptop seemed to be going in to low power mode
    which might have been interfering with the update process

3. stopped the failing update with ^C in the console, power
    cycled the XO, verified that the AP was fully connected
    and reran the 'olpc-update -r 8.2-760' from the console.
    This time it worked.

4. after the upgrade, the XOs appeared to work but when
    I tried to access the internet via my AP (which was shown
    as connected by the beautiful new indicator feature...great!)
    the connection was not made (from Browse activity)

5. rebooting both XOs fully resulted in full network operation

6. the software updates on both XOs failed with ViewSlides
    (on both) and Gmail (on the one where it was installed).

I've noticed that with some previous updates that an additional
reboot/power cycle sometimes was needed before full and
correct operation.
