We want to use the result in a shell pipeline hence use -P mode (pipe
mode) instead of -t mode (interactive tty mode) for systemd-run.
This shouldn't change much about the test, but is slightly more correct
(and quicker).
We have to invoke the tests as superuser, and not being able to read
the journal as the invoking user is annoying. I don't think there are
any security considerations here, since the invoking user can already
put arbitrary code in the Makefile and test scripts which get executed
with root privileges.
The logic to query test state was rather complex. I don't quite grok the point
of ret=$((ret+1))… But afaics, the precise result was always ignored by the
caller anyway.
We would remove stuff only if successful, so repeated invocations would
trivially fail.
Also drop "-f", so that if we expect to remove something, it must be there.
oomd works way better with swap, so let's make the test less flaky by
configuring a swap device for it. This also allows us to drop the ugly
`cat`s from the load-generating script.
Cover the case where a service is recovered out of reloading state via
a restart Restart= configuration.

This code was partially broken, since the firmware directory was
undefined. Also, some of the parts were a dead code, since they relied
on code from the original dracut test suite.
`command -v <bin> | grep ...` can under certain conditions cause the
`command` to exit with SIGPIPE, which in combination with `set -o
pipefail` means that the tests sometimes randomly die during setup.
Let's avoid using pipes in such cases.
This breaks some existing loops which previously ignored if the piped
program exited with EC >0. Rewrite them to mitigate this (and also make
them more robust in some cases).
The test appears to be occasionally failing. It uses systemd-run to echo
'hello world' into a namespaced journal and then uses journalctl to look for it,
but it doesn't wait.
In the failed runs it can't find it, but the automated journal dump shows
the message at the end.
Use --wait to avoid races.
'! grep -v' does *not* test that there are no matching lines.
Instead, it checks that whether there are any non-matching lines.
And of course, for the test to fail, '! grep' cannot be part of
an expression with &&.
We were grepping for 'hello world', and in the namespace we would
match on 'hello world', and outside, on 'echo "hello world"'. When
the condition check was fixed, the test gave a false positive.
We were invoking 'systemd-run bash', but the test invoked by bash
was not effective. When the result of that check is propagated, the
outer command fails.
