I am running into an odd issue that is supposedto be impossible.
pre-pivot/20write-ifcfg.sh is often being run but fails to write
net.*.ifcfg files because /tmp/net.ifaces does not exist at that moment.
The mount was otherwise successful, and rdbreak before switch_root sees
that /tmp/net.ifaces exists.
With plain "root=dhcp" with a NFS rootfs, it seems to never happen.
However with "root=dhcp bridge", perhaps 25-75% of the time it is
failing to write ifcfg files.
Some kind of race going on? An inspection of the code seems to me that
/tmp/net.ifaces should have already been created prior to pre-pivot?
This is not entirely unexpected due to the asynchronousness of
udev-events and the new initqueue/mount-loop.
The correct solution would be to move the whole call of netroot to the
initqueue, which we'll have to do anyway when we start handling
interface timeouts with arp.
