For all unit files foobar.service we will now read
foobar.service.d/*.conf, too. This may be used to override certain unit
settings without having to edit unit files directly.
This makes it really easy to change specific settings for services
without having to edit any unit file:
mkdir /etc/systemd/system/avahi-daemon.service.d/
echo -e '[Service]\nNice=99' > /etc/systemd/system/avahi-daemon.service.d/nice.conf
systemctl daemon-reload
Bootchart is renamed to 'systemd-bootchart' and installed as
/usr/lib/systemd/systemd-bootchart. The configuration file
will reside in /etc/systemd/bootchart.conf.
Adds is-failed to join is-active and is-enabled.
I grabbed this one from the todo list. Most of the functionality was
already there for is-active. I just needed to make check_one_unit take
the states to check for as an argument instead of the hardcoded
"active" and "reloading".
is-failed will return 1 if none of the units given are failed. This is
different from is-active which will return 3 if none of the units
given are active. It returns 3 with this comment:
/* According to LSB: "program is not running" */
As that does not make sense when looking for failed units I simply
chose 1 instead.
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.
This saves test output to individual .log files.
The driver is only used in /Makefile.am, not in
/docs/*udev/Makefile.am because the latter don't seem to work with
this driver. They don't produce much output anyway.
.gitignore is alphabetized, and .log files are added to it.
Generated files from /build-aux are removed from the list.
This introduces a new data threshold setting for sd_journal objects
which controls the maximum size of objects to decompress. This is
relieves the library from having to decompress full data objects even
if a client program is only interested in the initial part of them.
This speeds up "systemd-coredumpctl" drastically when invoked without
parameters.
Sometimes it is better to see messages in full, and the existing
set of options didn't allow this easily. E.g. now
journalctl -f --full
will behave like
tail -f /var/log/messages
of yore.
Long option only for now, since small letters are becoming
scarce, and this doesn't feel like a capital-letter-option.
'-u' would be nice, and the above command would be spelled
journalctl -fu
> Kay:
udev is early boot without /var. /var is entirely taboo for udev.
This partially reverts commit ee623f0d0c
(moving hwdb.bin is reverted, but the uninstall hook and cosmetic
changes remain).
The message catalog can be used to attach short help texts to log lines,
keyed by their MESSAGE_ID= fields. This is useful to help the
administrator understand the context and cause of a message, find
possible solutions and find further related documentation.
Since this is keyed off MESSAGE_ID= this will only work for native
journal messages.
The message catalog supports i18n, and is useful to augment english
language system messages with explanations in the local language.
This commit only includes short explanatory messages for a few example
message IDs, we'll add more complete documentation for the relevant
systemd messages later on.
A service that only sets the scheduling policy to round-robin
fails to be started. This is because the cpu_sched_priority is
initialized to 0 and is not adjusted when the policy is changed.
Clamp the cpu_sched_priority when the scheduler policy is set. Use
the current policy to validate the new priority.
Change the manual page to state that the given range only applies
to the real-time scheduling policies.
Add a testcase that verifies this change:
$ make test-sched-prio; ./test-sched-prio
[test/sched_idle_bad.service:6] CPU scheduling priority is out of range, ignoring: 1
[test/sched_rr_bad.service:7] CPU scheduling priority is out of range, ignoring: 0
[test/sched_rr_bad.service:8] CPU scheduling priority is out of range, ignoring: 100
Since we already allow defining the mode of AF_UNIX sockets and FIFO, it
makes sense to also allow specific user/group ownership of the socket
file for restricting access.
This was premarily intended to support the LSB facility $httpd which is
only known by Fedora, and a bad idea since it lacks any real-life
usecase.
Similar, drop support for some other old Fedora-specific facilities.
Also, document the rules for introduction of new facilities, to clarify
the situation for the future.
This adds SMACK label configuration options to socket units.
SMACK labels should be applied to most objects on disk well before
execution time, but two items remain that are generated dynamically
at run time that require SMACK labels to be set in order to enforce
MAC on all objects.
Files on disk can be labelled using package management.
For device nodes, simple udev rules are sufficient to add SMACK labels
at boot/insertion time.
Sockets can be created at run time and systemd does just that for
several services. In order to protect FIFO's and UNIX domain sockets,
we must instruct systemd to apply SMACK labels at runtime.
This patch adds the following options:
Smack - applicable to FIFO's.
SmackIpIn/SmackIpOut - applicable to sockets.
No external dependencies are required to support SMACK, as setting
the labels is done using fsetxattr(). The labels can be set on a
kernel that does not have SMACK enabled either, so there is no need
to #ifdef any of this code out.
For more information about SMACK, please see Documentation/Smack.txt
in the kernel source code.
v3 of this patch changes the config options to be CamelCased.
Network file systems generally do not offer inotify() that would work
across the network. We hence cannot rely on inotify() exclusiely in
those case. Provide an API to determine these cases, and suggest doing
manual regular rechecks.
Note that this is not complete yet, as we need to rescan journal dirs on
network file systems explicitly to find new/removed files
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
8bd3b8620c
Mostly useful for testing purposes. Setting Age to 1s works just as
well, but it is surprising that using 0s (or just 0) does not work.
Also clarify this in the documentation.
'systemd-coredumpctl' will list available coredumps:
PID UID GID sig exe
32452 500 500 11 /home/zbyszek/systemd/build/journalctl
32666 500 500 11 /usr/lib64/valgrind/memcheck-amd64-linux
...
'systemd-coredumpctl dump PID' will write the coredump
to specified file or stdout.
Given that "journalctl -u" exists now there's no need to duplicate this
functionality in systemctl, so let's drop this, especially given that it
always felt a bit awkward to overload "-f" to both --force and --follow,
and to have continues output with a status header for this.
systemctl status -f avahi-daemon
now becomes:
journalctl -fu avahi-daemon
Which is shorter and a lot less redundant.
The new 'unique' API allows listing all unique field values that a field
specified by a field name can take in all entries of the journal. This
allows answering queries such as "What units logged to the journal?",
"What hosts have logged into the journal?", "Which boot IDs have logged
into the journal?".
Ultimately this allows implementation of tools similar to lastlog based
on journal data.
Note that listing these field values will not work for journal files
created with older journald, as the field values are not indexed in
older files.
Much like logind has a client in loginctl, and journald in journalctl
introduce timedatectl, to change the system time (incl. RTC), timezones
and related settings.
As you likely know, Arch Linux is in the process of moving to systemd.
So I was reading through the various systemd docs and quickly became
baffled by this new abbreviation "resp.", which I've never seen before
in my English-mother-tongue life.
Some quick Googling turned up a reference:
<http://www.transblawg.eu/index.php?/archives/870-Resp.-and-other-non-existent-English-wordsNicht-existente-englische-Woerter.html>
I guess it's a literal translation of the German "Beziehungsweise", but
English doesn't work the same way. The word "respectively" is used
exclusively to provide an ordering connection between two lists. E.g.
"the prefixes k, M, and G refer to kilo-, mega-, and giga-,
respectively." It is also never abbreviated to "resp." So the sentence
"Sets the default output resp. error output for all services and
sockets" makes no sense to a natural English speaker.
This patch removes all instances of "resp." in the man pages and
replaces them with sentences which are much more clear and, hopefully,
grammatically valid. In almost all instances, it was simply replacing
"resp." with "or," which the original author (Lennart?) could probably
just do in the future.
The only other instances of "resp." are in the src/ subtree, which I
don't feel privileged to correct.

No longer override the default kernel font if nothing is specified in
vconsole.conf.
The default kernel font[0] provides ISO-8859-1 and box characters. Users
of Arabic, Cyrilic or Hebrew must set a different font manually as these
character sets were provided by the old default font [1], but are not
any longer.
Rationale:
* it is counter-intuitive that an empty vconsole.conf file is different
from adding FONT="";
* the version of the default font shipped with Arch (which is the
upstream one) behaves very badly during early boot[2] (which should
admittedly be fixed in the font itself);
* the kernel already supplies a default font, it seems reasonable to
use that unless anything else is specified;
* This also avoids a needless slow call to setfont; and
* We don't want to work around problems in the kernel (in case the
compiled-in font is not acceptable for whatever reason).
