This is useful e.g. if the keyfile is a raw device, where only parts of it
should be read. It is typically used whenever the keyfile-offset= option is
specified.

We want to keep things uniform, and hence treat udevd's man page like
any other in the repo. What matters is how users primarily interface
with a service, and that is not the binary path in /usr/lib/systemd but
the service name.
This reverts commit 6c1f3ba54a.
Instead of making systemd-udevd a so-link to systemd-udevd.service,
ship the real page as systemd-udevd to integrate better with distros
where udevd might be run standalone.
This should address TODO item "new dependency type to "group" services
in a target". Semantic of new dependency is as follows. Once configured
it creates dependency which will cause that all dependent units get
stopped if unit they all depend on is stopped or restarted. Usual use
case would be configuring PartOf=some.target in template unit file
and WantedBy=some.target in [Install] section and enabling desired
number of instances. In this case starting one instance won't pull in
target but stopping or starting target(in case of WantedBy is properly
configured) will cause stop/start of all instances.
systemd --version mirrors systemctl --version:
$ ./systemd --version
systemd 186
other
+PAM +LIBWRAP +AUDIT +SELINUX +IMA +SYSVINIT -LIBCRYPTSETUP
This information can be retrieved by other means (systemctl, etc.),
but it's easier for a newbie if 'systemd --version' says something
useful. And 'systemd --help' is already there, so let's complement
that with '--version'.
Previously, when the main data hash table grows too full the performance
simply started to decrease drastically. Instead, now simply rotate to a
new journal file as the hash table gets to full, so that we can start
with a new fresh empty hash table.
These printf specifiers allow us to refer to $HOME and $USER
in unit files. These are particularly helpful in instanced
units that have "User=" set, and in systemd --user domains.
The specifiers will return the pw_name and pw_dir fields
if the unit file has a User= field.
If the unit file does not have a User= field, the value
substituted is either $USER or $HOME from the environment,
or, if unset, the values from pw_name or pw_dir.
This patch is somewhat after Ran Benita's original patch,
which didn't get merged. I've split up the 2 specifiers
and extended them to do what is logically expected from
these specifiers.
Note that expansion is done at `start` time, not after
the units are parsed. Using `systemctl show` will just
show the specifiers.
all other dependencies are in 3rd person. Change BindTo= accordingly to
BindsTo=.
Of course, the dependency is widely used, hence we parse the old name
too for compatibility.
we now can take multiple matches, and they will apply as AND if they
apply to different fields and OR if they apply to the same fields. Also,
terms of this kind can be combined with an overreaching OR.
There's now sd_journal_new_directory() for watching specific journal
directories. This is exposed in journalctl -D.
sd_journal_wait() and sd_journal_process() now return whether changes in
the journal are invalidating or just appending.
We now create inotify kernel watches only when we actually need them
E.g. systemctl --all -t masked gives the list of masked units.
The -t/--type option is reused. This is possible because unit types
and unit load states are called differently, so it is possible to
distinguish what the user meant. Using the same option also means that
the interface is user for the user: less options to remember.
This is useful if your keyfile is a block device, and you want to
use a specific part of it, such as an area between the MBR and the
first partition.
This feature is documented in the Arch wiki[0], and has been supported
by the Arch initscripts, so would be nice to get this into systemd.
This requires libcryptsetup >= 1.4.2 (released 12.4.2012).
