gpt-auto-generator: add basic auto-discovery of GPT partitions
This adds a simple generator that is capable of automatically
discovering certain GPT partitions by their type UUID and mount/enable
them. This currently covers swap partitions and /home partitions, but is
expected to grow more features soon.
This currently doesn't handle LUKS encrypted /home.
logs-show: limit to 3 lines and use dots if not showing full message
So far, we would show up to 128 bytes from a message, simply
cutting of the rest. With multiline messages, it is quite common
for a message to be longer than that, and this model doesn't really
work anymore.
A new limit is added: up to 3 lines will be shown, unless --full is
used (c.f. first line below). The limit for bytes is extended to 300
bytes. An ellipsis will always be used, if some form of truncation
occurs. If the tail of the message is cut off, either because of
length or line limit, dots will be shown at the end of the last
line. If this last line is short, the dots will be simply appended. If
the last line is too long for that, it will be ellipsized with dots at
the very end.
Note that the limits are in bytes, not characters, and we suck at
outputting unicode strings (c.f. last three lines below).

fstab-generator: respect noauto/nofail when adding sysroot mount
Currently we don't respect noauto/nofail root mount options (from
rootflags kernel cmdline). We should map these two flags to the
corresponding boolean variable noauto and nofail when calling
add_mount().

udevd: respect the log-level set in /etc/udev/udev.conf
A regression introduced when we moved to systemd's logging is that the only
way to adjust the log-level of the udev daemon is via the env var, kernel
commandline or the commandline.
This reintroduces support for specifying this in the configuration file.

journal: handle multiline syslog messages
Since the journal can handle multiple lines just well natively,
and rsyslog can be configured to handle them as well, there is no need
to truncate messages from syslog() after the first newline.
Reproducer:
1. Add following four lines to /etc/rsyslog.conf
----------
$EscapeControlCharactersOnReceive off
$ActionFileDefaultTemplate RSYSLOG_SysklogdFileFormat
$SpaceLFOnReceive on
$DropTrailingLFOnReception off
----------
3. Restart rsyslog
# service rsyslog restart
4. Compile and run the following program
----------
#include <stdio.h>
#include <syslog.h>
int main()
{
syslog(LOG_INFO, "aaa%caaa", '\n');
return 0;
}
----------
Actual results:
Below message appears in /var/log/messages.
build-sys: link with librt if linking with libsd-daemon-int
In fba1ea0 'build: do not link everything with -lrt (and
therefore -pthread)' librt was removed from the list of
libraries. But libsd-daemon-internal also uses symbols from
librt and librt must thus be added everywhere where
libsd-daemon-interal is used, or otherwise linking might
fail:
/usr/bin/ld: ./.libs/libudev-core.a(sd-daemon.o): undefined reference to symbol 'mq_getattr@@GLIBC_2.3.4'
/usr/bin/ld: note: 'mq_getattr@@GLIBC_2.3.4' is defined in DSO /lib64/librt.so.1 so try adding it to the linker command line
pkg-config: export systemd{system,user}generatordir and catalogdir
We export the location of a bunch of directories this way,
so it makes sense to add those three. Especially catalogdir
is something that we want people to add things to.
Note on the naming: the first two are tied closely to systemd
itself, so I prefixed them with "systemd". The third one is
rather more generic, so no prefix.

zsh_completion: Speed up noncached perf of _journalctl

If two instances of test-fileio were run in parallel,
they could fail when trying to write the same file.
This predictable name in /tmp/ wasn't actually a security
issue, because write_env_file would not follow symlinks,
so this could be an issue only when running tests in
parallel.
logind: make sure login sessions are terminated with SIGHUP
bash ignores SIGTERM, and can only be terminated cleanly via SIGHUP.
Hence make sure that we the scope unit for the session is created with
SendSIGHUP enabled.

rework systemd's own process environment handling/passing
Stop importing non-sensical kernel-exported variables. All
parameters in the kernel command line are exported to the
initial environment of PID1, but suppressed if they are
recognized by kernel built-in code. The EFI booted kernel
will add further kernel-internal things which do not belong
into userspace.
The passed original environ data of the process is not touched
and preserved across re-execution, to allow external reading of
/proc/self/environ for process properties like container*=.
In case of scripts, _EXE is set to the interpreter name, and
_COMM is set based on the file name. Add a match for _COMM,
and _EXE if the interpreter is not a link (e.g. for yum,
the interpreter is /usr/bin/python, but it is a link to
/usr/bin/python2, which in turn is a link to /usr/bin/python2.7,
at least on Fedora, so we end up with _EXE=/usr/bin/python2.7).
I don't think that such link chasing makes sense, because
the final _EXE name is more likely to change.

build-sys: use pkg-config for python compilation flags
Python 2.7, and 3.2 and higher support querying compilation
flags through pkg-config. This makes python support follow
rules similar to various other optional compilation-time
libraries. New flags are called PYTHON_DEVEL_CFLAGS and
PYTHON_DEVEL_LIBS, because PYTHON (without _DEVEL), is
already used for the python binary name, and things would
be confusing if the same prefix was used for two things.
configure has --disable-python-devel to disable python modules.
One advantage is that CFLAGS for modules gets smaller:
- -I/usr/include/python3.3m -I/usr/include/python3.3m -Wno-unused-result -DDYNAMIC_ANNOTATIONS_ENABLED=1 -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv
+ -I/usr/include/python3.3m
as does LIBS:
- -lpthread -ldl -lutil -lm -lpython3.3m
+ -lpython3.3m
Support for Python 2.6 is removed, but can be easily
restored by using
PYTHON_DEVEL_CFLAGS="$(python2.6-config --cflags)",
etc., as ./configure parameters.
"systemctl load" has always been racy since the GC could hit any time,
before making use of the loaded unit. Very recent systemd will run GC
immeidately after all unit state changes which has the effect that the
the effect of "systemctl load" is completely gone now, so let's remove
the support for it in "systemctl" for good.
"systemctl set-log-level" is a command for analysis and tracing hence
"systemd-analyze" should be the better home for it, thus allowing us to
make the overly large "systemctl" a bit smaller.
systemctl: move "dump" command from systemctl to systemd-analyze
It's an analysis command and its format is explicitly not covered by any
stability guarantees, hence move away from systemctl and into
systemd-analyze, minimizing the already large interface of systemctl a
bit.
This patch also adds auto-paging to the various systemd-analyze commands
where that makes sense
