Lennart Poettering 82adf6af7c nspawn,man: use a common vocabulary when referring to selinux security contexts
Let's always call the security labels the same way:

  SMACK: "Smack Label"
  SELINUX: "SELinux Security Context"

And the low-level encapsulation is called "seclabel". Now let's hope we
stick to this vocabulary in future, too, and don't mix "label"s and
"security contexts" and so on wildly.

Michael Scherer 0d3f7bb3a5 exec: Add support for ignoring errors on SELinuxContext by prefixing it with -, like for others settings.
Also remove call to security_check_context, as this doesn't serve anything, since
setexeccon will fail anyway.

Michael Scherer 7b52a628f8 exec: Add SELinuxContext configuration item
This permit to let system administrators decide of the domain of a service.
This can be used with templated units to have each service in a différent
domain ( for example, a per customer database, using MLS or anything ),
or can be used to force a non selinux enabled system (jvm, erlang, etc)
to start in a different domain for each service.

Lennart Poettering 7f112f50fe exec: introduce PrivateDevices= switch to provide services with a private /dev
Similar to PrivateNetwork=, PrivateTmp= introduce PrivateDevices= that
sets up a private /dev with only the API pseudo-devices like /dev/null,
/dev/zero, /dev/random, but not any physical devices in them.

Jan Engelhardt e0e009c067 man: grammar and wording improvements
This is a recurring submission and includes corrections to:
- missing words, preposition choice.
- change of /lib to /usr/lib, because that is what most distros are
  using as the system-wide location for systemd/udev files.

Lennart Poettering 3fde5f30bd man: drop references to "cgroup" wher appropriate
Since cgroups are mostly now an implementation detail of systemd lets
deemphasize it a bit in the man pages. This renames systemd.cgroup(5) to
systemd.resource-control(5) and uses the term "resource control" rather
than "cgroup" where appropriate.

This leaves the word "cgroup" in at a couple of places though, like for
example systemd-cgtop and systemd-cgls where cgroup stuff is at the core
of what is happening.

Highligts in this particular commit:
- the "unsigned" type qualifier is completed to form a full type
  "unsigned int"
- alphabetic -> lexicographic (that way we automatically define how
  numbers get sorted)

David Strauss 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.

Zbigniew Jędrzejewski-Szmek 845c53246f man: add various filenames to the index
Everything which is an absolute filename marked with <filename></filename>
lands in the index, unless noindex= attribute is present. Should make
it easier for people to find stuff when they are looking at a file on
disk.

Various formatting errors in manpages are fixed, kernel-install(1) is
restored to formatting sanity.

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.

Michal Sekletar 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.

Zbigniew Jędrzejewski-Szmek ccc9a4f9ff man: extend systemd.directives(7) to all manual pages
New sections are added: PAM options, crypttab options, commandline
options, miscellaneous. The last category will be used for all
untagged <varname> elements.

Commandline options sections is meant to be a developer tool: when
adding an option it is sometimes useful to be able to check if
similarly named options exist elsewhere.

Frederic Crozat 0ae9c92a93 man: systemd.exec - explicit Environment assignment
Hi all,

while working on another bug, I discovered the "strange" way systemd is
parsing Environment= in .service and thought it was worth documenting
(because I don't expect people to find this syntax by themselves unless
they read the parsing code ;)

Be more verbose about using space in Environment field and not
using value of other variables

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=840260

[zj: expand and reformat the example a bit]

Michal Vyskocil 565d91fdf1 util: continuation support for load_env_file
Variable definitions can be written on more than one line - if each ends
with a backslash, then is concatenated with a previous one. Only
backslash and unix end of line (\n) are treated as a continuation.

Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58083

[zj: squashed two patches together; cleaned up grammar; removed
     comment about ignoring trailing backslash -- it is not ignored.]

Holger Hans Peter Freyther bb11271068 sched: Only setting CPUSchedulingPriority=rr doesn't work
A service that only sets the scheduling policy to round-robin
fails to be started. This is because the cpu_sched_priority is
initialized to 0 and is not adjusted when the policy is changed.

Clamp the cpu_sched_priority when the scheduler policy is set. Use
the current policy to validate the new priority.

Change the manual page to state that the given range only applies
to the real-time scheduling policies.

Add a testcase that verifies this change:

$ make test-sched-prio; ./test-sched-prio
[test/sched_idle_bad.service:6] CPU scheduling priority is out of range, ignoring: 1
[test/sched_rr_bad.service:7] CPU scheduling priority is out of range, ignoring: 0
[test/sched_rr_bad.service:8] CPU scheduling priority is out of range, ignoring: 100

Andrew Eikum 16dad32e43 Reword sentences that contain psuedo-English "resp."
As you likely know, Arch Linux is in the process of moving to systemd.
So I was reading through the various systemd docs and quickly became
baffled by this new abbreviation "resp.", which I've never seen before
in my English-mother-tongue life.

Some quick Googling turned up a reference:
<http://www.transblawg.eu/index.php?/archives/870-Resp.-and-other-non-existent-English-wordsNicht-existente-englische-Woerter.html>

I guess it's a literal translation of the German "Beziehungsweise", but
English doesn't work the same way. The word "respectively" is used
exclusively to provide an ordering connection between two lists. E.g.
"the prefixes k, M, and G refer to kilo-, mega-, and giga-,
respectively." It is also never abbreviated to "resp." So the sentence
"Sets the default output resp. error output for all services and
sockets" makes no sense to a natural English speaker.

This patch removes all instances of "resp." in the man pages and
replaces them with sentences which are much more clear and, hopefully,
grammatically valid. In almost all instances, it was simply replacing
"resp." with "or," which the original author (Lennart?) could probably
just do in the future.

The only other instances of "resp." are in the src/ subtree, which I
don't feel privileged to correct.
