iscsi-disk.rules: append to SYSTEMD_WANTS to avoid clobbering other rules
When testing with LVM over iscsi block devices, it was found that
the iscsi-disk.rules file rule clobbers additional SYSTEMD_WANTS values
that may already have been set by other disk rules. Fix by appending
our rules to the the environment variable.
New changelog entries:
[ Robert C Jennings & Dimitri John Ledkov ]
* If iscsi root was requested, but no iscsi devices were mounted, remove
the initramfs interfaces stamp file. Meaning, that on shutdown there
is no 30s delay, whilst trying to re-establish iscsi login to perform
a logout. LP: #1800681
New changelog entries:
* debian/tests/test-open-iscsi.py: Fix called process error.
If no image was available for a release, a NameError exception would be
raised.
debian/tests/test-open-iscsi.py: Fix called process error.
CalledProcessError is not a builtin error type, it comes from subprocess.
The bug here was that the test would not SkipTest if there was
no image available as intended.
