e8d2f6cde0 units: introduce remote-fs-setup.target to pull in dependencies from remote mounts
This introduces remote-fs-setup.target independently of
remote-fs-pre.target. The former is only for pulling things in, the
latter only for ordering.

The new semantics:

remote-fs-setup.target: is pulled in automatically by all remote mounts.
Shall be used to pull in other units that want to run when at least one
remote mount is set up. Is not ordered against the actual mount units,
in order to allow activation of its dependencies even 'a posteriori',
i.e. when a mount is established outside of systemd and is only picked
up by it.

remote-fs-pre.target: needs to be pulled in automatically by the
implementing service, is otherwise not part of the initial transaction.
This is ordered before all remote mount units.

A service that wants to be pulled in and run before all remote mounts
should hence have:

a) WantedBy=remote-fs-setup.target -- so that it is pulled in

b) Wants=remote-fs-pre.target + Before=remote-fs-pre.target -- so that
   it is ordered before the mount point, normally.

26687bf8a9 journal: Add sync timer to journal server
Add option to force journal sync with fsync. Default timeout is 5min.
Interval configured via SyncIntervalSec option at journal.conf. Synced
journal files will be marked as OFFLINE.

Manual sync can be performed via sending SIGUSR1.

d91c34f21f exec: Assigning the empty string to CapabilityBoundSet= should drop all caps
Previously, it would set all caps, but it should drop them all, anything
else makes little sense.

Also, document that this works as it does, and what to do in order to
assign all caps to the bounding set.

Seems natural to be able to specify relative directory,

in front-end code, not in the library.

c17ec25e4d core: reuse the same /tmp, /var/tmp and inaccessible dir
All Execs within the service, will get mounted the same
/tmp and /var/tmp directories, if service is configured with
PrivateTmp=yes. Temporary directories are cleaned up by service
itself in addition to systemd-tmpfiles. Directory which is mounted
as inaccessible is created at runtime in /run/systemd.

66e411811b sd-booted: update sd_booted() check a bit
Previously we were testing whether /sys/fs/cgroup/systemd/ was a mount
point. This might be problematic however, when the cgroup trees are bind
mounted into a container from the host (which should be absolutely
valid), which might create the impression that the container was running
systemd, but only the host actually is.

Replace this by a check for the existance of the directory
/run/systemd/system/, which should work unconditionally, since /run can
never be a bind mount but *must* be a tmpfs on systemd systems, which is
flushed at boots. This means that data in /run always reflects
information about the current boot, and only of the local container,
which makes it the perfect choice for a check like this.

(As side effect this is nice to Ubuntu people who now use logind with
the systemd cgroup hierarchy, where the old sd_booted() check misdetects
systemd, even though they still run legacy Upstart.)

9e5f0f9291 Make initrd.target the default target in the initrd
First, rename root-fs.target to initrd-root-fs.target to clarify its usage.

Mount units with "x-initrd-rootfs.mount" are now ordered before
initrd-root-fs.target. As we sometimes construct /sysroot mounts in
/etc/fstab in the initrd, we want these to be mounted before the
initrd-root-fs.target is active.

initrd.target can be the default target in the initrd.

7199aa96ce journalctl: show systemd messages about unit for -u
journalctl -u unit is not very useful, because it doesn't show
systemd messages about starting, stopping, coredumps, etc,
like systemctl status unit does. Make it show the same
information using the same rules.

If somebody really want to see just messages from by the unit,
it is easy enough to use _SYSTEMD_UNIT=...

700e07ffd5 add initrd-fs.target and root-fs.target
Instead of using local-fs*.target in the initrd, use root-fs.target for
sysroot.mount and initrd-fs.target for /sysroot/usr and friends.

Using local-fs.target would mean to carry over the activated
local-fs.target to the isolated initrd-switch-root.target and thus in
the real root. Having local-fs.target already active after
deserialization causes ordering problems with the real root services and
targets.

We better isolate to targets for initrd-switch-root.target, which are
only available in the initrd.

3ae390ba02 man: Document the actual behaviour of ExecStopPost

stopping the service with `systemctl stop foo.service`

However, that is not the case, as it also gets run when the service
unexpectedly exists, crashes, or gets SIGKILLed.

considered, but since we try to keep user visible documentation up to date,
showing the project version should be enough.

2cc8d9731a man/*.html: link to directives, python, guvev, libudev in headers
Since the HTML files are in different directories during build
and on fd.o, links are broken in the build directory. This could
be fixed by moving stuff around, or by modifying the files during
upload, but I think that people do not usually create HTML files
for local browsing, and this is not necessary.

a24c64f03f journald: introduce new "systemd-journal" group and make it own the journal files
Previously all journal files were owned by "adm". In order to allow
specific users to read the journal files without granting it access to
the full "adm" powers, introduce a new specific group for this.

"systemd-journal" has to be created by the packaging scripts manually at
installation time. It's a good idea to assign a static UID/GID to this
group, since /var/log/journal might be shared across machines via NFS.

This commit also grants read access to the journal files by default to
members of the "wheel" and "adm" groups via file system ACLs, since
these "almost-root" groups should be able to see what's going on on the
system. These ACLs are created by "make install". Packagers probably
need to duplicate this logic in their postinst scripts.

This also adds documentation how to grant access to the journal to
additional users or groups via fs ACLs.
