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.

Reindent man pages to 2ch

Use log "level" instead of "priority" The term "priority" is misleading because higher levels have lower priority. "Level" is clearer and shorter. This commit touches only the textual descriptions, not function and variable names themselves. "Priority" is used in various command-line switches and protocol constants, so completly getting rid of "priority" is hard. I also left "priority" in various places where the clarity suffered when it was removed.

man: add a mapping for external manpages It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?

doc: balance C indirections in function prototypes Shift the asterisks in the documentation's prototypes such that they are consistent among each other. Use the right side to match what is used in source code. Addendum to commit v209~82.

man: fix references to .pc files which aren't separate anymore

man: replace STDOUT with standard output, etc. Actually 'STDOUT' is something that doesn't appear anywhere: in the stdlib we have 'stdin', and there's only the constant STDOUT_FILENO, so there's no reason to use capitals. When refering to code, STDOUT/STDOUT/STDERR are replaced with stdin/stdout/stderr, and in other places they are replaced with normal phrases like standard output, etc.

man: resolve word omissions This is a recurring submission and includes corrections to: word omissions and word class choice.

man: improve grammar and word formatting in numerous man pages Use proper grammar, word usage, adjective hyphenation, commas, capitalization, spelling, etc. To improve readability, some run-on sentences or sentence fragments were revised. [zj: remove the space from 'file name', 'host name', and 'time zone'.]

man: fix spacing issue in various man pages Before: libsystemd-daemonpkg-config(1) After: libsystemd-daemon pkg-config(1) This fix is more complicated than it should be due to the consecutive XML elements separated by collapsible whitespace. Merging the lines and separating the XML elements with an en space or a non-breaking space is the only solution that results in one, and only one, space being inserted between them when testing. An em space results in two spaces being inserted.

man: use <constant> for various constants which look ugly with quotes

man: typo fixes https://bugs.freedesktop.org/show_bug.cgi?id=55890 Fixed typos, serial comma, and removed "either" as there were more than two options. Also did an extra rename of "system-shutdown" to "systemd-shutdown" that was forgotten in commit 8bd3b8620c80d0f2383f2fb04315411fc8077ca1
