Change in UUID format breaks connections on upgrades


I am working with a large OLPC deployment in Nicaragua performing a
software upgrade. The previous software release included
NetworkManager- and the new one includes

After performing the upgrade, NetworkManager does not connect to any
of the wireless networks that it used to. The files are still there in
/etc/NetworkManager/system-connections, but it is like they are

Looking in the logs:

keyfile: parsing FZT_Cisco_AP
Connection failed to verify: (unknown)
keyfile: error: invalid or missing connection property

It looks like at some point, NM has changed its UUID format, and has
stopped accepting the old one, which is like this:

Would it be possible to relax this check so that compatibility is retained?

I would be happy to send in a patch that tweaks nm_utils_is_uuid() accordingly.
