8d98da3f11 journalctl: allow the user to specify the file(s) to use
This is useful for debugging and feels pretty natural. For example
answering the question "is this big .journal file worth keeping?"
is made easier.

5302ebe15f journal: add sd_journal_open_files
This allows the caller to explicitly specify which journal files
should be opened. The same functionality could be achieved before
by creating a directory and playing around with symlinks. It
is useful to debug stuff and explore the journal, and has been
requested before.

Waiting is supported, the journal will notice modifications on
the files supplied when opening the journal, but will not add
any new files.

3f3a438f58 journalctl: add --system/--user flags
--user basically gives messages from your own systemd --user services.
--system basically gives messages from PID 1, kernel, and --system
services. Those two options are not exahustive, because a priviledged
user might be able to see messages from other users, and they will not
be shown with either or both of those flags.

a688baa8b7 journal: add ability to filter by current user
This is the just the library part.

SD_JOURNAL_CURRENT_USER flags is added to sd_j_open(), to open
files from current user.

SD_JOURNAL_SYSTEM_ONLY is renamed to SD_JOURNAL_SYSTEM,
and changed to mean to (also) open system files. This way various
flags can be combined, which gives them nicer semantics, especially
if other ones are added later.

Backwards compatibility is kept, because SD_JOURNAL_SYSTEM_ONLY
is equivalent to SD_JOURNAL_SYSTEM if used alone, and before there
we no other flags.

12f25b6e74 Standardize on 'file system' and 'namespace' in man pages.
This change is based on existing usage in systemd and online.
'File-system' may make sense in adjectival form, but man pages
seem to prefer 'file system' even in those situations.

3f92e4b4b6 utmp: turn systemd-update-utmp-shutdown.service into a normal runtime service
With this change systemd-update-utmp-shutdown.service is replaced by
systemd-update-utmp.service which is started at boot and stays around
until shutdown. This allows us to properly order the unit against both
/var/log and auditd.

c35b956d34 units: rework systemd-random-seed-{load,save}.service to be a single service
That way ordering it with MountsRequiredFor= works properly, as this no
longer results in mount units start requests to be added to the shutdown
transaction that conflict with stop requests for the same unit.

9d995d54b5 Add support for ConditionSecurity=ima
Just as with SMACK, we don't really know if a policy has been
loaded or not, as the policy interface is write-only. Assume
therefore that if ima is present in securityfs that it is
enabled.

Update the man page to reflect that "ima" is a valid option
now as well.

b62ee5249d condition, man: Add support for ConditionSecurity=smack
According to Documentation/security/Smack.txt:
  In keeping with the intent of Smack, configuration data is minimal
  and not strictly required. The most important configuration step is
  mounting the smackfs pseudo filesystem.
This means that checking the mount point should be enough.

19adb8a320 systemd-sleep: add support for freeze and standby
A new config file /etc/systemd/sleep.conf is added.
It is parsed by systemd-sleep and logind. The strings written
to /sys/power/disk and /sys/power/state can be configured.
This allows people to use different modes of suspend on
systems with broken or special hardware.

Configuration is shared between systemd-sleep and logind
to enable logind to answer the question "can the system be
put to sleep" as correctly as possible without actually
invoking the action. If the user configured systemd-sleep
to only use 'freeze', but current kernel does not support it,
logind will properly report that the system cannot be put
to sleep.

http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html

SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed
since they were used in only a few places and with the
addition of /etc/systemd/sleep.conf it becomes easier to just
append the name of each file to the dir name.

8f51399e75 kernel-install: add default install scripts
Do the depmod in the kernel-install hooks, so hooks can produce/install
kernel modules and be part of the depmod.

Also move the basic boot loader entry creation and removal to a
plugin script.

If PRETTY_NAME is not defined in /etc/os-release, fallback to
PRETTY_NAME="Linux $KERNEL_VERSION".

Add documentation for everything in the man page.

00d1818bb7 man: we need to be more careful with the unit search paths we document
We generally document the suggested paths, not the paths possible in
weird, non-standard setups. We do this in order to not confuse
administrators/users unnecessarily and to push people to install things
into the same directories on all distributions.

We are PID 1 after all, the really basic building block of the OS.
Unlike for an app there's very little benefit in being entirely
relocatable.
