Because do-tests runs the restore-defaults script, fstab would get reset
to the default version and the mount point wouldn't be available anymore
after stopping and restarting the guests (unless the guest images were
rebuilt in between).
The wrapper called the command twice for any unit but "strongswan" and
it didn't return the correct exit code. This was noticed when an
if-updown script tried to check if systemd-resolved is active and always
succeeded, which caused failing attempts to configure it.
But now that the return code is correct, trying to enable bind9 won't
fail silently anymore if the unit doesn't exist (similar on older systems
for named), so this is adapted.
This avoids having to copy testresults, makes results of cancelled runs
browsable (runs may actually be followed live) and preserves old results
when rebuilding guest images (e.g. when using the build-strongswan script).
The number of consecutive test runs without any intermittent rebuild of the
guest images is also not limited by the image size anymore.
It is still compatible with the current release as the config in
sites-available will be ignored, while conf-enabled does not exist and
is not included in the main config.
This script can be used in pretest.dat files to wait until an IPsec
connection becomes available. This avoids unconditional sleeps and
improves test performance.
The ipv6 tests have been updated to use the expect-connection script.
