These packages include binaries that link to a static version of
libsystemd-shared, so they don't depend on the systemd-libs package at
runtime.
These packages are intended to expose systemd-tmpfiles and systemd-sysusers
to non-systemd systems, such as container images.
Note that static linking only pulls in the small subset of functions from
libsystemd-shared that are actually used by the binaries, so the total size of
a statically linked binary is much smaller than the sum of the shared binary
with the shared library. The resulting binaries on an x86_64 build have 272KB
(tmpfiles) and 180KB (sysusers).
This commit relies on the -Dstandalone-binaries=true build configuration that
was pushed upstream in PR 16061 and released in systemd v246.
Previous method was untenable, because rpm doesn't have a concept of
put those files here, and the rest in there. So for every positive
pattern that was added, we had to add an %exclude line somewhere else.
So let's generate the lists using pattern matching. This is a bit messy
too, but should not require updates when files are added or removed.
(Sometimes it'll be necessary to add a new pattern if the new files
should not land in the main binary package.)
There's some intentional changes:
- man pages are more consistently included with the files they describe
- shell completion scripts similarly
- various kernel-install and modules-load related files are moved
to -udev subpackage
