Bug Description
=== Begin SRU Information ===
[Impact]
Open-iscsi's /etc/init/
the 'ipconfig' code in the client writes a file named /run/${DEVICE}.conf
The klibc in 12.04 writes that file to /tmp. This is simply a verison
and expectation mismatch between klibc and open-iscsi in 12.04.
It can result in the network interface upon which the iscsi target
resides being brought down, as /etc/init/
longer functions correctly.
With a network block-device under your root filesystem, bringing
down the network is not good.
The fix here is done in the initramfs and should be forwards compatible.
If a file has been written named /tmp/net-
has *not* been written /run/net-
/tmp to /run. That will later be picked up by iscsi-network-
which will then function correctly.
[Test Case]
its easy to see that if the net-DEVICE.conf file is not written in
/run, then the code in /etc/init/
the desired affect.
[Regression Potential]
There should not be much chance for regression here. Likely, fallout
would be limited to iscsi root instances.
[Other Info]
The maas "ephemeral images" have been using this patch for several
months, and the changes are the same as applied in quantal.
=== End SRU Information ===
This bug was initially opened with misunderstanding.
The issue present is that open-iscsi's upstart job expects ipconfig files to be in /run, but they are written by ipconfig in precise to /tmp.
