3a54a15760 man: use same header for all files
The "include" files had type "book" for some raeason. I don't think this
is meaningful. Let's just use the same everywhere.

$ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n  "http^gms' man/*.xml

fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

0c69794138 tree-wide: remove Lennart's copyright lines
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.

818bf54632 tree-wide: drop 'This file is part of systemd' blurb
This part of the copyright blurb stems from the GPL use recommendations:

https://www.gnu.org/licenses/gpl-howto.en.html

The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.

hence, let's just get rid of this old cruft, and shorten our codebase a
bit.

bda7d78ba1 pid1: preserve current value of log target across re-{load,execution}
To make debugging easier, this patches allows one to change the log target and
do reload/reexec without modifying configuration permanently, which makes
debugging easier.

Indeed if one changed the log target at runtime (via the bus or via signals),
the change was lost on the next reload/reexecution.

In order to restore back the default value (set via system.conf, environment
variables or any other means ), the empty string in the "LogTarget" property is
now supported as well as sending SIGTRMIN+26 signal.

To make debugging easier, this patches allows one to change the log level and
do reload/reexec without modifying configuration permanently, which makes

Indeed if one changed the log max level at runtime (via the bus or via

23b27b39d2 terminal: add internal API to format URLs for display in capable terminals
Newer terminals (in particular gnome-terminal) understand special escape
sequence for formatting clickable links. Let's support that to make our
tool output more clickable where that's appropriate.

For details see this:

https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda

The one big issue is that 'less' currently doesn't grok this, and
doesn't ignore sequence like regular terminal implementations do if they
don't support it. Hence for now, let's disable URL output if a pager is
used. We should revisit that though as soon as less added support for it
and enough time passed for it to enter various distributions.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

d60cb656fc manager: fix job mode when signalled to shutdown etc
The irreversible job mode is required to ensure that shutdown is not
interrupted by the activation of a unit with a conflict.

We already used the correct job mode for `ctrl-alt-del.target`.  But not
for `exit.target` (SIGINT of user manager).  The SIGRT shutdown signals
also needed fixing.

Also change SIGRTMIN+0 to isolate default.target, instead of starting
it.  The previous behaviour was documented.  However there was no reason
given for it, nor can we provide one.  The problem that isolate is too
aggressive anywhere outside of emergency.target (#2607) is orthogonal.
This feature is "accessible by different means and only really a safety
net"; it is confusing for it to differ from `systemctl default` without
explanation.

`AllowIsolate=yes` is retained on poweroff.target etc. for backwards
compatibility.

`sigpwr.target` is also an obvious candidate for linking to a shutdown
target.  Unforunately it is also a possible hook for implementing some
logic like system V init did, reading `/etc/powerstatus`.  If we switched
to starting `sigpwr.target` with REPLACE_IRREVERSIBLY, attempts to run
`systemctl shutdown` from it would fail, if they had not thought to set
`DefaultDependencies=no`.  We had provided no examples for `sigpwr`, and
the whole idea is cruft to keep legacy people happy.  For the moment, I
leave `sigpwr` alone, with no risk of disrupting anyone's
previously-working, half-working, or untested setup.

Fixes #6484.  See also #6471

This updates the man page for the changes introduced in 1d84ad9445.
"=" is kep if the option is predominantly used with an argument, and dropped
otherwise.

v2:
 - update also description of log_color
 - drop '=' in all cases where it is optional
   (previous rule of dropping it only in some cases was just too arbitrary.)

1eecafb8c1 man: use unicode ellipsis in more places
As requested in
https://github.com/systemd/systemd/pull/4864#pullrequestreview-12372557.

docbook will substitute triple dots for the ellipsis in man output, so this has
no effect on the troff output, only on HTML, making it infinitesimally nicer.

In some places we show output from programs, which use dots, and those places
should not be changed. In some tables, the alignment would change if dots were
changed to the ellipsis which is only one character. Since docbook replaces the
ellipsis automatically, we should leave those be. This patch changes all other
places.

7d5ceb6416 core: allow to redirect confirmation messages to a different console
It's rather hard to parse the confirmation messages (enabled with
systemd.confirm_spawn=true) amongst the status messages and the kernel
ones (if enabled).

This patch gives the possibility to the user to redirect the confirmation
message to a different virtual console, either by giving its name or its path,
so those messages are separated from the other ones and easier to read.

acf553b04d terminal-util: use getenv_bool for $SYSTEMD_COLORS
This changes the semantics a bit: before, SYSTEMD_COLORS= would be treated as
"yes", same as SYSTEMD_COLORS=xxx and SYSTEMD_COLORS=1, and only
SYSTEMD_COLORS=0 would be treated as "no". Now, only valid booleans are treated
as "yes". This actually matches how $SYSTEMD_COLORS was announced in NEWS.

36b4a7ba55 Remove snapshot unit type
Snapshots were never useful or used for anything. Many systemd
developers that I spoke to at systemd.conf2015, didn't even know they
existed, so it is fairly safe to assume that this type can be deleted
without harm.

The fundamental problem with snapshots is that the state of the system
is dynamic, devices come and go, users log in and out, timers fire...
and restoring all units to some state from the past would "undo"
those changes, which isn't really possible.

Tested by creating a snapshot, running the new binary, and checking
that the transition did not cause errors, and the snapshot is gone,
and snapshots cannot be created anymore.

New systemctl says:
Unknown operation snapshot.
Old systemctl says:
Failed to create snapshot: Support for snapshots has been removed.

IgnoreOnSnaphost settings are warned about and ignored:
Support for option IgnoreOnSnapshot= has been removed and it is ignored

4cf0b03b97 core: change how crash_shell and crash_reboot interact
Instead of freezing in PID1 and letting the forked child freeze or
reboot when exec("/bin/sh") fails, just wait for the child's
exit and then do the freeze_or_reboot in PID1 as usual.

This means that when both crash_shell and crash_reboot are enabled, the
system will reboot after the shell exits.

8dd4c05b54 core: add support for naming file descriptors passed using socket activation
This adds support for naming file descriptors passed using socket
activation. The names are passed in a new $LISTEN_FDNAMES= environment
variable, that matches the existign $LISTEN_FDS= one and contains a
colon-separated list of names.

This also adds support for naming fds submitted to the per-service fd
store using FDNAME= in the sd_notify() message.

This also adds a new FileDescriptorName= setting for socket unit files
to set the name for fds created by socket units.

This also adds a new call sd_listen_fds_with_names(), that is similar to
sd_listen_fds(), but also returns the names of the fds.

systemd-activate gained the new --fdname= switch to specify a name for
testing socket activation.

This is based on #1247 by Maciej Wereski.

Fixes #1247.

b9e74c3994 core: rework crash handling
This introduces a new systemd.crash_reboot=1 kernel command line option
that triggers a reboot after crashing.

This also cleans up crash VT handling. Specifically, it cleans up the
configuration setting, to be between 1..63 or a boolean. This is to
replace the previous logic where "-1" meant disabled. We continue to
accept that setting, but only document the boolean syntax instead.

This also brings the documentation of the default settings in sync with
what actually happens.

The CrashChVT= configuration file setting is renamed to CrashChangeVT=,
following our usual logic of not abbreviating unnecessarily. The old
setting stays support for compat reasons.

12b42c7667 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.

681eb9cf2b 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.
