Well not a perfect long term solution... but for the moment perhaps
really an idea.

Which probably explains why with allow-hotplug, I no longer saw services
which couldn't bind to their respective addresses.

Doesn't that basically mak the ifup at .service useless?

okay...

Done (with the v2 patch, of course). I did about 5-7 boots for each of
the two, the network always came up by "itself" (i.e. my cron script
never needed to repair things), and in both cases, it seemed that all
the services could bind to their addresses.

Sure :-(


Thanks so far :)
