proot provides userspace-powered emulation of chroot and mount --bind,
lending it to be used on environments without unprivileged user
namespaces, or in otherwise restricted environments like Android.
In order to achieve this, proot makes use of the kernel's ptrace()
facility, which we can use in order to detect its presence. Since it
doesn't use any kind of namespacing, including PID namespacing, we don't
need to do any tricks when trying to get the tracer's metadata.
For our purposes, proot is listed as a "container", since we mostly use
this also as the bucket for non-container-but-container-like
technologies like WSL. As such, it seems like a good fit for this
section as well.
Given that ANSI_COLOR= is mostly about branding it probably makes sense
to use RGB rather than paletted colors for them, so that the colors
match the project design as close as possible. Hence, provide a 25bit
RGB example for ANSI_COLOR, and update the overall example to something
newer.

The wiki was primarily describing the D-Bus API, but it also had a large
introduction to the daemon functionality. I moved that latter part into
the page that describes the daemon, and the API description into the new
page.
This is mostly a straighforward import. Apart from some required formatting
changes, I removed obvious repetitions, and made tiny grammar and typo fixes
where I noticed them. The goal is not to have a perfect text immediately.
<interfacename>org.foo.bar</interface> is used for interface names,
<function>function()</function> for methods, and <function>signal</function>
(no parentheses) for signal names. In D-Bus, signals are similar to methods,
and docbook doesn't have a nice tag for them.
First After=local-fs-pre.target wasn't described in the man page although it's
part of the default dependencies automatically set by pid1.
Secondly, Before=local-fs.target was only set if the automount unit was
generated from the fstab-generator because the dep was explicitly
generated. It was also not documented as a default dependency.
Fix it by managing the dep from pid1 instead.
This patch changes the way user managers set the default umask for the units it
manages.
Indeed one can expect that if user manager's umask is redefined through PAM
(via /etc/login.defs or pam_umask), all its children including the units it
spawns have their umask set to the new value.
Hence make user units inherit their umask value from their parent instead of
the hard coded value 0022 but allow them to override this value via their unit
file.
Note that reexecuting managers with 'systemctl daemon-reexec' after changing
UMask= has no effect. To take effect managers need to be restarted with
'systemct restart' instead. This behavior was already present before this
patch.
Fixes#6077.
A warning is emitted from sd_bus_message_{get,set}_priority. Those functions
are exposed by pystemd, so we have no easy way of checking if anything is
calling them.
Just making the functions always return without doing anything would be an
option, but then we could leave the caller with an undefined variable. So I
think it's better to make the functions emit a warnings and return priority=0
in the get operation.
For whatever reason, this does not get rendered propely in the man
page and results in an invalid code:
W: manual-page-warning /usr/share/man/man7/systemd.special.7.gz 103: warning: macro `AQ' not defined
We say 'user manager' and 'system manager' in most other places, so let's just
use this form here too.
Merging by hand because github refuses merging because "Rebasing the commits of
this branch on top of the base branch cannot be performed automatically as this
would create a different result than a regular merge.".
Consumers of the sd-bus convenience API can't make convenience
helpers of their own without va_list variants.
This commit is a mechanical change splitting out the existing function
bodies into bare va_list variants having a 'v' suffixed to the names.
The original functions now simply create the va_list before forwarding
the call on to the va_list variant, and the va_list variants dispense
with those steps.
For now, this function is nearly equivalent to the si_uint64 parser, except for
an additional range check as Linux only takes 32-bit values as bitrates. In
future, this may also be used to introduce fancier bitrate config formats.
