TEST-34 complains in `test_check_writable` when running with gcov, as
the build directory tree is not writable with DynamicUser=true. As I had
no luck with $GCOV_PREFIX and other runtime gcov configuration, let's
just ignore the gcov errors for this test.
We want to test four things:
- that the transient units are successfully started when drop-ins exist
- that the transient setings override the defaults
- the drop-ins override the transient settings (the same as for a normal unit)
- that things are the same before and after a reload
To make things more fun, we start and stop units in two different ways: via
systemctl and via a direct busctl invocation. This gives us a bit more coverage
of different code paths.
Slices are worth testing too, because they don't need a fragment path so they
behave slightly differently than service units. I'm making this a separate
patch from the actual tests that I wanted to add later because it's complex
enough on its own.
clear_services() is renamed to clear_units() and now takes a full
unit name including the suffix as an argument.
_clear_service() is renamed to clear_unit() and changed likewise.
create_service() didn't have the same underscore prefix, and I don't think
it's useful or needed for a local function, so it is removed.
No functional change.
The glibc stuff on ppc64le C8S is a little bit wild, as there are two
versions:
```
$ ldconfig -p | grep libc.so
libc.so.6 (libc6,64bit, hwcap: "power9", OS ABI: Linux 3.10.0) => /lib64/glibc-hwcaps/power9/libc-2.28.so
libc.so.6 (libc6,64bit, OS ABI: Linux 3.10.0) => /lib64/libc.so.6
```
and with `/etc/ld.so.cache` present all binaries use the first one:
```
$ ldd /bin/cat
linux-vdso64.so.1 (0x00007fffa8070000)
libc.so.6 => /lib64/glibc-hwcaps/power9/libc-2.28.so (0x00007fffa7e20000)
/lib64/ld64.so.2 (0x00007fffa8090000)
```
However, without the cache the binaries will fall back to `/lib64/libc.so.6`
which breaks tests that use the minimal verity images (like TEST-29),
because we install only the first version (that's shown by `ldd` at
the time the images are created):
```

```
```
$ chroot /var/tmp/systemd-test.nMHPfc/minimal/
/bin/bash: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
```
With the ldconfig's cache it seems to work as expected:
```
$ chroot /var/tmp/systemd-test.gVtYLg/minimal
bash-4.4# cat --version
cat (GNU coreutils) 8.30
...
```
The iscsi-init.service calls `sh` which might, in certain circumstances,
pull in instrumented systemd NSS modules causing `sh` to fail. Let's mitigate
this by pulling in an env file crafted by `create_asan_wrapper()` that
(among others) pre-loads ASan's DSO.
Allows to skip check that ensures units must not be running.
I have a use case that would use reattach, except the orchestrator
is using a non-standard versioning scheme, so image matching cannot
work. As a workaround, need to be able to detach and then attach
manually, without stopping the units to avoid extended downtimes
and loss of FD store.
Let's remove some sleep loops, and instead:
1. Use Type=notify to wait until "resolvectl monitor" successfully
installed its monitor, so that we know that queries enqueued later
will definitely be seen.
2. Use "grep -m1" to watch "journalctl -f" output to wait precisely for
the RR data we want to see, and immediately exit.
This shortens code quite a bit, and should make it more robust.
Otherwise we might read an incomplete log and fail:

Since open-iscsi 2.1.2 [0] the initiator name should be generated via
a one-time service instead of distro package's post-install scripts.
However, some distros still use this approach even after this patch,
so prefer the already existing initiatorname.iscsi file if it exists.

In most cases we refernced the concept as "initrd". Let's convert most
remaining uses of "initramfs" to "initrd" too, to stay internally
consistent.
This leaves "initramfs" only where it's relevant to explain historical
concepts or where "initramfs" is part of the API (i.e. in
/run/initramfs).

If a root hash is specified, we should be checking that it matches
the root hash in the verity signature partition, so let's not skip
processing of the verity signature partitions if a root hash is
specified.
