Now, actually check if the environment variable names and values used
are valid, before accepting them. With this in place are at some places
more rigid than POSIX, and less rigid at others. For example, this code
allows lower-case environment variables (which POSIX suggests not to
use), but it will not allow non-UTF8 variable values.
All in all this should be a good middle ground of what to allow and what
not to allow as environment variables.
(This also splits out all environment related calls into env-util.[ch])
I can't find a reason why we shouldn't try to output messages for other
unit types than .service, .socket, .mount and .swap as well. It's probably
a leftover from before we started logging UNIT= from inside PID 1.
The ability to start a new unit with 'systemctl start ...' should not
depend on whether there are other units in the directory. Previously,
an additional 'systemctl daemon-reload' would be necessary to tell
systemd to update the list of unit lookup paths.
This allows one templated unit to refer to another templated unit
at installation time.
Examples:
> grep WantedBy ~/.config/systemd/user/mpop@.timer
WantedBy=services@%i.target
> srv disable mpop@iit.timer
rm '/home/alxchk/.config/systemd/user/services@iit.target.wants/mpop@iit.timer'
> srv enable mpop@iit.timer
ln -s '/home/alxchk/.config/systemd/user/mpop@.timer' '/home/alxchk/.config/systemd/user/services@iit.target.wants/mpop@iit.timer'

cppcheck reported:
[src/bootchart/svg.c:791]: (error) Mismatching allocation and deallocation: f
This allows us to print simple performance data of all parts of the boot now:
- firmware
- boot loader
- kernel
- initrd
- userspace
This only works for bootloaders which support passing TSC data via EFI
variables. As of now that's only gummiboot.
Variable definitions can be written on more than one line - if each ends
with a backslash, then is concatenated with a previous one. Only
backslash and unix end of line (\n) are treated as a continuation.
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58083
[zj: squashed two patches together; cleaned up grammar; removed
comment about ignoring trailing backslash -- it is not ignored.]
Document continuation support in systemd.exec
systemctl list-dependencies lists all unit's dependecies and
recursively expands all subsidiary target units into a tree.
Primary purpose for this command is to show all units which are
enabled in specified target.
New file output.h with output flags and modes.
--full parameter also for cgls and loginctl.
Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup,
show_cgroup_and_extra, show_cgroup_and_extra_by_spec).
get_process_cmdline with max_length == 0 will not ellipsize output.
Replace LINE_MAX with 0 in some calls of get_process_cmdline.
[zj: Default to --full when under pager for clgs.
Drop '-f' since it wasn't documented and didn't actually work.
Reindent a bit.

For "systemctl snapshot" it makes no sense to complete an incomplete
name with ".service" as we previously did, use ".snapshot" instead.
Also, don't bother with mount units or suchlike, we know that this must
be a snapshot and hence is the only sane way for completion.
As it turns out the bus properties for timer units wre really broken,
so let's clean this up for good and properly add calendar timer
serialization. We really should get that right before finalizing the
bus API documentation in the wiki...
Adding UNIT= to log lines allows them to be shown
in 'systemctl status' output, etc.
A new set of macros and functions is added. This allows for less
verbose notation than using log_struct() explicitly.
The set of logging functions is expanded to take a pair of arguments
(e.g. "UNIT=" and the RHS) which add an extra line to the structured
log entry. This can be used to add macros which add a different
identifier later on.
