Was getting:
../src/id128/id128.c:15:1: error: initializer element is not constant
static sd_id128_t arg_app = SD_ID128_NULL;
^
when building on CentOS 7.
Other parts of the code initialize `static sd_id128_t` to {} and this
was the original setting before a19fdd66c2 anyways.
This sould make our test suite a bit more robust if it is slow running.
A few of our test services use StandardOutput=tty or StandardError=tty
in the tests in order to connect test services to the container console.
This gets into conflict with the container getty which wants exclusive
access to the console. Since the container getty is started with
Type=idle it typically gets started after a timeout only if the TTY is
already used, which hence introduces a race: if the test finishes
earlier all is good, if not, then the test gets kicked off the TTY which
then causes bash to abort since it cannot write any error messages
anymore.
Let's fix this hence: all tests that connect to the tty are now
synchronized to getty-pre.target, so they finish before any getty is
started.
Note that this slightly changes behaviour: "none" is only allowed as
option, if it's the only option specified, but not in combination with
other options. I think this makes more sense, since it's the choice when
no options shall be specified.
It's not really clear which PAM errors to use for which conditions, but
something called PAM_SYSTEM_ERR should probably not be used when the
error is not the result of some system call failure.
This makes the naming more consistent: we now have
bootctl systemd-efi-options,
$SYSTEMD_EFI_OPTIONS
and the SystemdOptions EFI variable.
(SystemdEFIOptions would be redundant, because it is only used in the context
of efivars, and users don't interact with that name directly.)
bootctl is adjusted to use 2sp indentation, similarly to systemctl and other
programs.
Remove the prefix with the old name from 'bootctl systemd-efi-options' output,
since it's redundant and we don't want the old name anyway.
This cleans up and unifies the outut of --help texts a bit:
1. Highlight the human friendly description string, not the command
line via ANSI sequences. Previously both this description string and
the brief command line summary was marked with the same ANSI
highlight sequence, but given we auto-page to less and less does not
honour multi-line highlights only the command line summary was
affectively highlighted. Rationale: for highlighting the description
instead of the command line: the command line summary is relatively
boring, and mostly the same for out tools, the description on the
other hand is pregnant, important and captions the whole thing and
hence deserves highlighting.
2. Always suffix "Options" with ":" in the help text
3. Rename "Flags" → "Options" in one case
4. Move commands to the top in a few cases
5. add coloring to many more help pages
6. Unify on COMMAND instead of {COMMAND} in the command line summary.
Some tools did it one way, others the other way. I am not sure what
precisely {} is supposed to mean, that uppercasing doesn't, hence
let's simplify and stick to the {}-less syntax
And minor other tweaks.
Our handling of the condition was inconsistent. Normally, we'd only fire when
the file was created (or removed and subsequently created again). But on restarts,
we'd do a "recheck" from path_coldplug(), and if the file existed, we'd
always trigger. Daemon restarts and reloads should not be observeable, in
the sense that they should not trigger units which were already triggered and
would not be started again under normal circumstances.
Note that the mechanism for checks is racy: we get a notification from inotify,
and by the time we check, the file could have been created and removed again,
or removed and created again. It would be better if we inotify would give as
an unambiguous signal that the file was created, but it doesn't: IN_DELETE_SELF
triggers on inode removal, not directory entry, so we need to include IN_ATTRIB,
which obviously triggers on other conditions.
Fixes#12801.
