Previously all journal files were owned by "adm". In order to allow
specific users to read the journal files without granting it access to
the full "adm" powers, introduce a new specific group for this.
"systemd-journal" has to be created by the packaging scripts manually at
installation time. It's a good idea to assign a static UID/GID to this
group, since /var/log/journal might be shared across machines via NFS.
This commit also grants read access to the journal files by default to
members of the "wheel" and "adm" groups via file system ACLs, since
these "almost-root" groups should be able to see what's going on on the
system. These ACLs are created by "make install". Packagers probably
need to duplicate this logic in their postinst scripts.
This also adds documentation how to grant access to the journal to
additional users or groups via fs ACLs.
Errors because of oom conditions or descriptor exhaustion should not
be ignored. We probably cannot recover from those conditions.
Current behaviour wrt. insufficient permissions is described in the
man page. It might make sense in case of user sessions, so I left
it as is.
* python-systemd-reader:
python-systemd: rename Journal to Reader
build-sys: upload python documentation to freedesktop.org
systemd-python: add Journal class for reading journal
python: build html docs using sphinx
journalct: also print Python code in --new-id
python: utilize uuid.UUID in logging
python: add systemd.id128 module
... and 34 other commits
In short: python module systemd.id128 is added, and existing
systemd.journal gains a new class systemd.journal.Reader, which can be
used to iterate over journal entries. Documentation is provided, and
accessible under e.g.
pydoc3 systemd.journal.Reader
or
firefox http://www.freedesktop.org/software/systemd/man/python-systemd/
This reverts commit cb96a2c69a.
It is not a mistake to pass args when -b is specified. They will simply
be passed on to the container's init.
The manpage needs fixing, that's true.
Occasionally people report problem with reboot/poweroff operations hanging in
the middle. One known cause is when a new transaction to start a unit is
enqueued while the shutdown is going on. The start of the unit conflicts with
the shutdown jobs, so they get cancelled. The failure case can be quite unpleasant,
becase getty and sshd may already be stopped.
Fix it by using irreversible jobs for shutdown (reboot/poweroff/...) actions.
This applies to commands like "reboot", "telinit 6", "systemctl reboot". Should
someone desire to use reversible jobs, they can say "systemctl start reboot.target".`
Add a new job mode: replace-irreversibly. Jobs enqueued using this mode
cannot be implicitly canceled by later enqueued conflicting jobs.
They can however still be canceled with an explicit "systemctl cancel"
call.
"systemctl default" should behave identically to "telinit N" (where N is the
corresponding runlevel target number), therefore it should use isolate job mode
too.
In systemd-bootchart, the disk model information will not be found
unless the root device is specified using `root=/dev/sdxY` on the kernel
line. Just add a note as to why this doesn't happen.
Turning off filtering with --filter is just too confusing.
Config option "Filter" doesn't have to be changed, here
"Filter=yes" already meant to filter.
This makes 'status' behave like 'list-units':
systemctl status -> status of all units
systemctl -t error status -> status of error units
systemctl -t mount status -> etc.
Essentially transfer the 'README' file in src/bootchart to the man page
for easier reading by users.
Moved the 'History' section to the bottom, before the 'See Also' section.

systemd-nspawn will now print the PID of the child.
An example showing how to enter the container is added
to the man page.
Support for nsenter without an explicit command was
added in https://github.com/karelzak/util-linux/commit/5758069
(post v2.22.2). So this example requires both a new kernel
and the latest util-linux.
Option listings seemed to be pretty much random, some were short opt,
long opt, others were long opt, short opt. This just makes every option
with a short and long opt that I could find in the order short opt, long
opt, for formatting's sake.
This unifies much of the logic behind them:
- All four will now ofllow the rule that the earlier file and earlier
assignment in the .d/ directories wins. Before, sysctl was the only
outlier, where the later setting always won.
- All four now support getopt() and --help on the command line.
- All four can now handle specification of configuration file names on
the command line to apply. The tools will automatically find them, and
apply them. Previously only tmpfiles could do that. This is useful for
%post scripts in RPMs and suchlike.
- This fixes various error path issues in conf_files_list()
