AC_CHECK_FILE fails when cross-compiling. It is intended to be used to
check for files that are used at runtime during build time (e.g.
/etc/passwd, /dev/*) [1]. For files which are only used at build time
'test -f' is sufficient.

This drops the libsystemd-terminal and systemd-consoled code for various
reasons:
* It's been sitting there unfinished for over a year now and won't get
finished any time soon.
* Since its initial creation, several parts need significant rework: The
input handling should be replaced with the now commonly used libinput,
the drm accessors should coordinate the handling of mode-object
hotplugging (including split connectors) with other DRM users, and the
internal library users should be converted to sd-device and friends.
* There is still significant kernel work required before sd-console is
really useful. This includes, but is not limited to, simpledrm and
drmlog.
* The authority daemon is needed before all this code can be used for
real. And this will definitely take a lot more time to get done as
no-one else is currently working on this, but me.
* kdbus maintenance has taken up way more time than I thought and it has
much higher priority. I don't see me spending much time on the
terminal code in the near future.
If anyone intends to hack on this, please feel free to contact me. I'll
gladly help you out with any issues. Once kdbus and authorityd are
finished (whenever that will be..) I'll definitely pick this up again. But
until then, lets reduce compile times and maintenance efforts on this code
and drop it for now.
While 235c6e6 gets LTO builds running again, it goes back to using fat
LTO objects instead of using gcc-{ar,nm,ranlib}. Building these fat
objects takes significantly more time.
Use the suggested solution and look for gcc-{ar,nm,ranlib}, which launch
the binutils tools with the appropriate --plugin parameter. GCC versions
that do not ship these should either default to -ffat-lto-objects or do
not support LTO at all.
On another note, nm from binutils 2.25 seems to be smart enough to load
the LTO plugin when needed without having to specify --plugin.
Similar to SmackProcessLabel=, if this configuration is set, systemd
executes processes with given SMACK label. If unit has
SmackProcessLabel=, this config is overwritten.
But, do NOT be confused with SMACK64EXEC of execute file. This default
execute process label(and also label which is set by
SmackProcessLabel=) is set fork-ed process SMACK subject label and
used to access the execute file.
If the execution file has also SMACK64EXEC, finally executed process
has SMACK64EXEC subject.
While if the execution file has no SMACK64EXEC, the executed process
has label of this config(or label which is set by
SmackProcessLabel=). Because if execution file has no SMACK64EXEC then
excuted process inherits label from caller process(in this case, the
caller is systemd).
Currently, 'make distcheck' fails with an error such as this:
srcdir=../../po /usr/bin/intltool-update -m
The following files contain translations and are currently not in use.
Please consider adding these to the POTFILES.in file, located in the po/ directory.
build2/src/core/org.freedesktop.systemd1.policy.in
build3/src/core/org.freedesktop.systemd1.policy.in
[...]
This is caused by a new behavior of autmake 1.15 which changed the
location of the build tree during 'make distcheck', and the fact that
intltool doesn't yet ignore that paths.
We used to have a workaround in configure.ac that makes the failing call
a no-op, but it was accidentially removed in 23756070
("remove gudev and gtk-doc").
Bring back that snipet for now, until intltool and automake sorted out
their issues and like each other again.

./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.
If no kdbus kernel support is available, dbus-dameon will be used.
With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.
With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.
Unfortunately, gcc keeps warning about those even when we use an
explicit (void) cast to indicate we are not interested in the result.
LLVM's clang does not have that issue and works fine with the casts.
GCC bug being tracked at:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425
Until that GCC bug is fixed (and the version with the fix is in
many/most distributions) or we switch to LLVM as the default compiler,
it looks like we'll have to disable this warning by default...
Tested by building files known to present warnings about unused results
without the suppression, confirmed that the warnings were no longer
present with this patch applied.
This partially reverts commit 00c11bc53a ("build-sys: don't suppress irrelevant warnings").
Make the build sys error out on missing function prototypes, missing
variable declarations, implicit function declarations or forgotten return
statements.
None of these conditions are acceptable, and by making them hard errors, the
build bots can detect them earlier.
This way, development builds will not rely on gc-sections to
paper over cyclic link dependencies. Newly introduced broken
link requirements will immediatley fail.
Since we introduced AX_NORMALIZE_PATH, using --with-rootprefix=/ does
produce an empty string, but using --with-rootprefix= (empty) now
produces "." instead which is wrong.
Work around it until we can find a better solution for AX_NORMALIZE_PATH
upstream at autoconf-archive.
Bug: https://github.com/systemd/systemd/issues/54
Strip trailing slashes from options such as --with-rootprefix, so that building
with rootprefix="/" results in paths like "/lib" instead of "//lib".
Also handle paths such as "/usr/" gracefully.
Use m4/ax_normalize_path.m4 from the autoconf-archive project, which is now
included in our tree as per usual practices in using autoconf-archive macros.
Tested with the following configure options:
./configure \
--with-rootprefix=/ \
--with-rootlibdir=/lib64/ \
--prefix=/usr/ \
--libdir=/lib/ \
--with-bashcompletiondir=/bash-completion/completions/
(The "prefix" and "libdir" are already automatically normalized by Autoconf,
this command is testing the others.)
Compared the config.log and resulting trees (in particular man pages) to
confirm double slashes were not present in the latter.
Also tested that a configuration using default options is not affected and that
`make distcheck` still works as expected.
Previously we always ran distcheck with --disable-split-usr. This caused
test-path-util to fail with
Assertion 'fsck_exists("minix") == 0' failed at ../src/test/test-path-util.c:224, function test_fsck_exists(). Aborting.
as looking up fsck.minix would only look into DEFAULT_PATH_NORMAL, but on these
systems fsck is in /sbin/.
Introduce /usr/lib/systemd/systemd-sysv-install [--root=] <action> <name>
abstraction, replacing the direct calling of chkconfig. This allows
distributions to call their specific tools like update-rc.d without patching
systemd.
Ship systemd-sysv-install.SKELETON as an example for packagers how to implement
this.
Drop the --enable-chkconfig configure option.
Document this in README and point to it in NEWS.
