Subject: Race condition? /tmp/net.ifaces and pre-pivot
Date: Thu, 23 Jul 2009 17:37:44 -0400 [thread overview]
Message-ID: <4A68D828.40506@redhat.com> (raw)
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?
