I talked to Michael Biebl, some notes:

 * I suppose due to keeping the root fs readonly the entire boot is a tad faster and thus exposes the race.
 * Due to that race it is recommended that physical interfaces use 'allow-hotplug', and virtual interfaces (bridges etc) use 'auto'.
 * debian-installer uses allow-hotplug for writing /etc/network/interfaces, to cope with slow detection on the kernel side

However, it also doesn't work with allow-hotplug, I'll investigate further.
