3e3852b3c6 core: make "tmpfs" dependencies on swapfs a "default" dep, not an "implicit"
There should be a way to turn this logic of, and DefaultDependencies=
appears to be the right option for that, hence let's downgrade this
dependency type from "implicit" to "default, and thus honour
DefaultDependencies=.

This also drops mount_get_fstype() as we only have a single user needing
this now.

A follow-up for #7076.

fab35afabf mount: make sure we unmount tmpfs mounts before we deactivate swaps (#7076)
In the past we introduced this property just for tmp.mount. However on
todays systems usually there are many more tmpfs mounts. Most notably
mounts backing XDG_RUNTIME_DIR for each user.

Let's generalize what we already have for tmp.mount and implement the
ordering After=swap.target for all tmpfs based mounts.

5dfcb8d200 units: add 'SmackFileSystemRoot=*' option into tmp.mount
If SMACK is enabled, 'smackfsroot=*' option should be specified when
/tmp is mounted since many non-root processes use /tmp for temporary
usage. If not, /tmp is labeled as '_' and smack denial occurs when
writing.

In order to do that, 'SmackFileSystemRoot=*' is newly added into
tmp.mount.

29a3f0d4c5 Revert "units: add 'smackfsroot=*' option into tmp.mount when SMACK is enabled"
This reverts commit 409c2a13fd.

It breaks the bootup of systems which enable smack at compile time, but have no
smack enabled in the kernel. This needs a different solution.

8ebf02d6f3 units: skip mounting /tmp if it is a symlink
We shouldn't get confused if people have symlinked /tmp somewhere, so
let's simply skip the mount then.

d0114527f4 units: don't order tmp.monut after local-fs-pre.target
Since tmp.mount is a tmpfs this is not necesary, and should speed up boot marginally.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.

623ac9d2fc units: mount /tmp as tmpfs
The default setups should be a stateless as possible. /tmp as tmpfs is
the intended default for general purpose systems.

Small temporary files should not be stored on disk; lager files, or
files which should potentially survive a reboot, belong into /var/tmp.

Also catch up with some good old UNIX history.

More details are here:
