Primarily, use the new multi-line support in table formatting.
Also, stream-line naming of the "max-addresses" options. We used three
names for the concept internall, let's just unify on the name we use for
this for external users, i.e. "max-addresses".
In the wiki, this was a separate page. I don't think this split is useful,
since the information about what is stable and what not seems randomly split
between the two pages.
Links are adjusted for our own pages. Some external links to gentoo and other
projects seem to be broken, but it's a chore to fix them.
Instead of saying that patches for portability are not accepted, say that this
is decided case-by-case. This is what happens in practice, and we tend to
discuss each patch on its own merits.
Some sentences are reworded a bit where they sound awkward.
In subsequent commits, calls to if_nametoindex() will be replaced by a wrapper
that falls back to alternative name resolution over netlink. netlink support
requires libsystemd (for sd-netlink), and we don't want to add any functions
that require netlink in basic/. So stuff that calls if_nametoindex() for user
supplied interface names, and everything that depends on that, needs to be
moved.
We don't need a seperate output parameter that is of type int. glibc() says
that the type is "unsigned", but the kernel thinks it's "int". And the
"alternative names" interface also uses ints. So let's standarize on ints,
since it's clearly not realisitic to have interface numbers in the upper half
of unsigned int range.
If we have a template unit template@.service, it should be allowed to specify a
dependency on a unit without an instance, bar@.service. When the unit is created,
the instance will be propagated into the target, so template@inst.service will
depend on bar@inst.service.
This commit changes unit_dependency_name_compatible(), which makes the manager
accept links like that, and unit_file_verify_alias(), so that the installation
function will agree to create a symlink like that, and finally the tests are
adjusted to pass.
This mostly reuses existing checkers used by pid1, so handling of aliases
should be consistent. Hopefully, with the test it'll be clearer what it
happening.
Support for .wants/.requires "aliases" is restored. Those are still used in the
wild quite a bit, so we need to support them.
See https://github.com/systemd/systemd/pull/13119 for a discussion of aliases
with an instance that point to a different template: this is allowed.
