This introduces a new setting TemporaryFileSystem=. This is useful
to hide files not relevant to the processes invoked by unit, while
necessary files or directories can be still accessed by combining
with Bind{,ReadOnly}Paths=.
The touchpad toggle key (Fn + Esc) on the T-bao Tbook air sends CTRL +
META + scancode 0x76 without this quirk. With this quirk it sends CTRL +
META + F21, with F21 mapping to XF86TouchpadToggle, which is what we want.
Note that the CTRL + META modifiers being send together with the F21 are
still somewhat unusual, userspace will need to be thought to deal with
this as there is nothing we can do about this at the hwdb level. Note at
least one other laptop also sends CTRL + META + F21 instead of just F21.

without this quirk. With this quirk it sends CTRL + META + F21, with F21

config_parse_join_controllers would free the destination argument on failure,
which is contrary to our normal style, where failed parsing has no effect.
Moving it to shared also allows a test to be added.
The arguments have to be indentical everywhere, so let's use a macro to
make things more readable. But only in the headers, in the .c files let's
keep them verbose so that it's easy to see the argument list.
Coverity now started warning about this ("Calling unlinkat without checking
return value (as is done elsewhere 12 out of 15 times).", and it is right:
most of the time we should at list print a log message so people can figure
out something is wrong when this happens.
v2:
- use warning level in journald too (this is unlikely to happen ever, so it
should be safe to something that is visible by default).
In the parse logic `line_get_key_value()` in sd-boot treats spaces
and tabs are valid spacing between key and value in the line.
So, let's use the same logic for `bootctl` and the others which read
sd-boot configs.
Fixes#8154.
Apply defaults for system_{uid,gid}_max even if the /etc/login.defs file
doesn't exist (e.g. in Clear Linux with no changes).
awk returns an empty string in case the file doesn't exist, causing meson to
fail in to_int(). So set the default if output is empty. This makes the BEGIN{}
blocks unnecessary, so remove them.
The comment above says we're truncating the string but that's not true,
an assert will fail in xsprintf if the description is longer than
LINE_MAX.
Let's use snprintf instead of xsprintf to make sure it's truncated.
We'll cast its result to void to tell static checkers we're fine with
truncation.
The single quote working with multiple lines is likely to be unintended. With
current versions of meson, it also causes error messages after it to report the
wrong line number. Use the documented syntax instead.
To successfully extract strings from our .policy files, gettext needs
polkit.{its,loc} files provided by policykit-devel. When that package is not
installed, systemd-pot would fail to extract strings:
[0/1] Running external command systemd-pot.
xgettext: warning: file 'src/core/org.freedesktop.systemd1.policy.in.in' extension 'policy' is unknown; will try C
xgettext: warning: file 'src/hostname/org.freedesktop.hostname1.policy.in' extension 'policy' is unknown; will try C
...
We now don't need the .its and .loc files for normal building, but they are
still useful when generating the .pot file, because that way we avoid the
dependency on sufficiently new polkit. We just need to tell i18n to pass their
location to xgettext.
intltool is unnecessary since c81217920e.
But we still need gettext, because we use msgformat to generate .mo files.
(I tried to make meson depend on it, at least in Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=1545926, but that didn't fly,
and in Debian at least meson also has no dependency on the tools used by
its i18n module, so we need to add our own dependency anyway.)
Closes#8192.
Those files don't contain any @variables@, so the configuration step was just
copying them to build/. Let's avoid that, and fix their suffixes while at it.
This usually is very annoying to users who then cannot log in, so
make sure we always warn if that happens (selinux, or whatever other reason).
