Public bug reported:
[Impact]
* Currently the initramfs-tools autopkgtest fails for at least AMD64, with the
following signature:
"mount: /tmp/autopkgtest.K1r92h/build.zdS/src/mnt: special device /dev/loop0p1
does not exist."
* The reason for that is the test trying immediately to use that
partition on the loop device, but kernel may not have a partition re-
read ioctl issued, so the test may fail as observing a nonexistent
partition.
* The fix proposed here is just to manually run "partprobe" before using
the new to-be-discovered loop partition in the net autopkgtest.
[Test Case]
* Build initramfs-tools in PPA and observe the failure in AMD64 - the signature
of the failure is as discussed in the Impact section above.
[Regression Potential]
* Extremely low potential, we are just introducing a partition re-read/probe
operation during autopkgtest phase, in order to keep the partition table of
loop devices consistent before the test uses it.
* The only potential issue I see with that is if for some reason we don't have
partprobe in the autopkgtest environment, but that shouldn't happen since
parted package is on ubuntu-standard.
* Notice that this test is not executed in Debian CI given that CI has
no support for VMs, and this test requires that.
