By defining rootprefix= we avoid a double slash in $systemdsystemunitdir and
other variables. This fixes a regression introduced in
1c2c7c6cb3d92315624f3711114e86b0acfbce63 where the variables using rootprefix=/
would start with a double slash. This should be interpreted the same, but is
certainly ugly.
The rootprefix variable was added to systemd.pc in
1c2c7c6cb3d92315624f3711114e86b0acfbce63, so there is no question of backwards
compatiblity. If people try to "override" the prefix and specify
--define-variable=rootprefix=/, they will get a double slash, which should be
OK, and is the same as --define-variable=rootprefix=/something/, which also
results in a double slash somewhere in the strings.

Fixes #4549.
People want to be able to redefine the prefixes relative to which the other
variables are defined. Something like
pkgconf --define-variable=prefix=/home/user/installpath --variable=systemdsystemunitdir systemd
I'm not convinced that this entirely useful, because the installed systemd will
not look at those paths, but maybe it's OK as an alternative type of $DESTDIR.
This has been requested a few times over the years, so let's just provide this.
I thought this would be more complicated, since we allow all kinds of directories
to be overrides in the compilation configuration. But it turns out that all the
directories defined in systemd.pc are relative to three prefixes:
$prefix, $rootprefix, and $sysconfdir. So this patch adds $rootprefix and $sysconfdir
to the .pc file and then changes the subsequent definitions in the .pc file to use
them. In the end we define each path twice using the same rules: once in meson.build
and once in the .pc file.
Without overrides:

echo -n "$i = "; pkgconf --with-path=$PWD/build/src/core --variable=$i systemd

(pkgconf doesn't provide a way to print all variables together with their definitions,

Let's not use atoi() if we can simply provide the project version as a number.
In C code, this is the numerical project version. In substitutions in other
files, this is just the bare substitution.
The "PACKAGE_" prefix is from autotools, and is strange. We call systemd a
"project", and "package" is something that distros build. Let's rename.
PACKAGE_URL is renamed to PROJECT_URL for the same reasons and for consistency.
(This leave PACKAGE_VERSION as the stringified define for C code.)

Also, export these ranges in our pkg-config files.

The original idea of systemd.pc was to contain arch-independent system
and systemd information. By exposing libdir as part of the fields (added
in eb39a6239c631873db62f6a942e6cb3dab0a2db4), it started to carry
arch-dependent data, thus breaking multilib systems. It was then moved
to pkgconfiglibdir to deal with this (in
aec432c6134146e138124c4130be2ee89dca07fa), but actually the right
approach is to simply not include libdir in the .pc file at all.
THis patch hence more or less reverts both commits again, and moves the
.pc file back into pkgconfigdatadir.
As alternative for querying the systems primary libdir there's now
"systemd-path system-library-arch", hence a more correct alternative
exists for querying this variable from the .pc file.

There's little reason to export this, so let's drop it to minimize the
file a bit.
|
| |
|

This is useful for code that tries to figure out the primary arch's
$libdir on the local system, given that is different on the various
Linuxes.

We shouldn't destroy IPC objects of system users on logout.

This introduces SYSTEM_UID_MAX defined to the maximum UID of system
users. This value is determined compile-time, either as configure switch
or from /etc/login.defs. (We don't read that file at runtime, since this
is really a choice for a system builder, not the end user.)
While we are at it we then also update journald to use SYSTEM_UID_MAX
when we decide whether to split out log data for a specific client.

We export the location of a bunch of directories this way,
so it makes sense to add those three. Especially catalogdir
is something that we want people to add things to.
Note on the naming: the first two are tied closely to systemd
itself, so I prefixed them with "systemd". The third one is
rather more generic, so no prefix.
