man: document automatic dependencies For all units ensure there's an "Automatic Dependencies" section in the man page, and explain which dependencies are automatically added in all cases, and which ones are added on top if DefaultDependencies=yes is set. This is also done for systemd.exec(5), systemd.resource-control(5) and systemd.unit(5) as these pages describe common behaviour of various unit types.

man: revert dynamic paths for split-usr setups This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.

man: generate configured paths in manpages In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

man: fix a bunch of links All hail linkchecker!

man: boilerplate unification

Reindent man pages to 2ch

man: fix references to systemctl man page which is now in section 1 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760613

man: wording and grammar updates This is a recurring submission and includes corrections to various issue spotted. I guess I can just skip over reporting ubiquitous comma placement fixes… 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)

man: use <literal> not <filename> for suffixes Especially sentences like "filename ends in .suffix" are easier to parse if the suffix is surrounded by quotes. In sentences like "requires a .service unit", where the suffix is used as a class designation, there is no need to use quotes.

core/path: catch errors when adding watches Errors because of oom conditions or descriptor exhaustion should not be ignored. We probably cannot recover from those conditions. Current behaviour wrt. insufficient permissions is described in the man page. It might make sense in case of user sessions, so I left it as is.

man: use <replaceable> in various places

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.

units: for all unit settings that take lists, allow the empty string for resetting the lists https://bugzilla.redhat.com/show_bug.cgi?id=756787

man: add links to directive index to see-alsos systemd.directives(5) is renamed to systemd.directives(7). Section 7 is "Miscellaneous".

man: typo fixes Fixes a few more typos. Also changes a "Accept=no" to "Accept=false" to be consistent with the previous examples in the same man page.

man: reword man page titles Make sure the man page titles are similar in style and capitalization so that our man page index looks pretty.

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.

path: add PathModified (= PathChanged + IN_MODIFY)

man: document that PathChanged= does not care for simple writes but only for close()-after-write()

path,unit: support globbing in conditions and path units

path: optionally, create watched directories in .path units

update man pages for recent changes

man: various man page updates

man: trivial spelling fixes

man: document path units
