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: boilerplate unification

Reindent man pages to 2ch

man: add hostnamed chassis type "embedded" to machine-info(5) man machine-info lacks hostnamed chassis type "embedded" as introduced in 218. The following lines should fix this.

hostnamed: introduce new location machin-info field, too

Add DEPLOYMENT to hostnamectl [zj: remove the check against a fixed list of environments.]

hostnamed: update documentation with new "watch" chassis type

doc: resolve missing/extraneous words or inappropriate forms Issues fixed: * missing words required by grammar * duplicated or extraneous words * inappropriate forms (e.g. singular/plural), and declinations * orthographic misspellings

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: 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'.]

hostnamed: make chassis type configurable via /etc/machine-info For many usecases it is useful to store the chassis type somewhere, and /etc/machine-info sounds like a good place. Ideally we could always detect the chassis type from firmware, but frequently that's not available and in many embedded devices probably entirely unrealistic. This patch adds a configurable setting CHASSIS= to /etc/machine-info and exposes this via hostnamectl/hostnamed. hostnamed will guess the chassis type from DMI if nothing is set explicitly. I also added support for detecting it from ACPI, which should be more useful as ACPI 5.0 actually knows a "tablet" chassis type, which neither DMI nor previous ACPI versions knew. This also enables DMI-based and ACPI-based detection for non-x86 systems as ACPI is apparently coming to ARM platforms soon. I tried to minimize the vocabulary of chassis types understood and added: desktop, laptop, server, tablet, handset. This is much less than either APCI or DMI know. If we need more types later on we can easily add them.

hostname: add new hostnamectl tool as text client for hostnamed

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.

man: corrected machine-info(5) man page to be in line with source change conflicting man/machine-info.xml documentation to match functionality in src/hostname/hostnamed.c 114-119

hostnamed: introduce systemd-hostnamed http://www.freedesktop.org/wiki/Software/systemd/hostnamed
