Let's say you have two initscripts, A and B:
A contains in its LSB header:
Required-Start: C
and B contains in its LSB header:
Provides: C
When systemd is parsing /etc/rc.d/, depending on the file order, you
can end up with either:
- B is parsed first. An unit "C.service" will be "created" and will be
added as additional name to B.service, with unit_add_name. No bug.
- A is parsed first. An unit "C.service" is created for the
"Required-Start" dependency (it will have no file attached, since
nothing provides this dependency yet). Then B is parsed and when trying
to handle "Provides: C", unit_add_name is called but will fail, because
"C.service" already exists in manager->units. Therefore, a merge should
occur for that case.
The manager already prints "Time has been changed" at level info. It
seems too verbose to print the time change message additionally for
every waiting timer unit.
Downgrade the per-unit message to debug.
This alos gets rid of explicit sd_open_fd() and sd_open_address()
constructors in favour of sd_new() + sd_new_start() where the
negotiation parameters may be set it in between.
Setting MaxRetentionSec= caused the kernel log to overflow and the
journal daemon to enter an endless loop.
Logging from the journald main loop gets directed to /dev/kmsg,
which wakes up journald again. We skip the import of this message
by checking for our own PID, but this still causes the main loop
to never go to sleep again because we never stopped logging from
there.
With the conversion from pci-db + usb-db to hwdb, the property
got accitentially renamed.
Move the name back to the long established identifier *MODEL*
instead of *PRODUCT*.

static nodes (like /dev/loop-control) are created when systemd-udevd
is started and needed to mount loopback devices. Therefore,
local-fs-pre.target should be only started after systemd-udevd is
started.
While most folks will be using the derivative from user-session-units,
I'm updating this one to reflect some of the fixes and things to note
about user sessions:
- cgroup should be set with "%u" - username instead of %I
- set dbus path with %U explicitly too
- hint to folks that wish to use MEM_CG features in user sessions
- allow unit to be enabled for instances with systemctl enable
Some code really wants to know whether there was a string list parsed,
so don't take the shortcut here, and always allocate a string list, even
if it is an empty one.

src/libsystemd-bus/bus-message.h:41:1: warning: attribute 'packed' is ignored, place it after
"struct" to apply attribute to type declaration [-Wignored-attributes]
Requesites are not supposed to be auto-started afterall, they are just
checks, so don't try to be smarter here than appropriate.
Based on a patch from Michal Schmidt.
This reverts commit faeffa73a8.
There isn't really much point in dropping the Conflicts= since shutting
down this service is basically free as it doesn't have anything running.
Also, the patch was incomplete, because shutdown.target was still listed
in Before=.
Distributions that never shipped upstart do not have
"telinit" in /lib/upstart/..
Defaults to /lib/upstart/telinit so there is no change
for systems existing installs.
- Reword messages a bit
- Correct check whether EACCES is in the set of errors
- Don't complain if no journal files are found
- allocate Set object for errors lazily since in the best case we don't
need it at all.
- don't consider it an error if /run/log/journal doesn't exist (because
that's the usual case actually, if storage is enabled)
Some parts of systemd (at least the DBus activation codepath) "reply"
to signals, which of course have the no-reply flag set. We will be
defensive here and still send out a reply if we're passed a signal.

Previously, it would set all caps, but it should drop them all, anything
else makes little sense.
Also, document that this works as it does, and what to do in order to
assign all caps to the bounding set.

Ensure clients don't overflow usec_t when doing relative time changes.
This is mostly just paranoia and protection against accidents, after all
clients are already authenticated, and they can se the time to any
value they wish anyway, but better be safe than sorry.

gcc does not know that errno cannot be negative, and warns
about unitialized variables later on. Kill the warnings by
returning -errno only after checking that errno is positive.
There are many ways in which we can get those checks wrong, so it is
better to warn and then error out on a real access failure.
The error messages are wrapped to <80 lines, because their primary
use is to be displayed in the terminal, and it is easier to read them
this way. Reading them in the journal can be a bit trickier, but
this is a bug in logs-show.c.
If we notice that we unprivileged and not in any of the groups which
have access to /var/log/journal, print a nice message about which groups
do.
This checks and prints all groups that are in the default ACL for
/var/log/journal, which is not necessarily correct for all journal
files, but pretty close.
