Tom Gundersen noticed a regression where comment=systemd.automount in
fstab no longer prevented the adding of the After=foo.mount dependency
into local-fs.target. He bisected it to commit 9ddc4a26.
It turns out that clearing the default_dependencies flag is necessary
after all, in order to avoid complementing of Wants= with After= in the
target unit. We still want to add the dependencies on quota units and
umount.target though.

Always use the macros for downcasting.
Remove a few obviously pointless casts.
|
|
The UNIT() macro upcasts from specific unit types to the base Unit.
Use it everywhere, rather than accessing the 'meta' member directly.
|
|
Now that objects of all unit types are allocated the exact amount of
memory they need, the Unit union has lost its purpose. Remove it.
"Unit" is a more natural name for the base unit class than "Meta", so
rename Meta to Unit.
Access to members of the base class gets simplified.

The storage of the unit objects on the heap is currently not very
efficient. For every unit object we allocate a chunk of memory as large
as the biggest unit type, although there are significant differences in
the units' real requirements.
pahole shows the following sizes of structs:
488 Target
496 Snapshot
512 Device
528 Path
560 Timer
576 Automount
1080 Socket
1160 Swap
1168 Service
1280 Mount
Usually there aren't many targets or snapshots in the system, but Device
is one of the most common unit types and for every one we waste
1280 - 512 = 768 bytes.
Fix it by allocating only the right amount for the given unit type.
On my machine (x86_64, with 39 LVM volumes) this decreases systemd's
USS (unique set size) by more than 300 KB.

quotacheck.service and quotaon.service were not pulled in for fstab mounts.
Fix it by not clearing the default_dependencies flag.
The root filesystem may have quotas too, so don't check for "/" there.
No need to have duplicate code for adding dependencies on umount.target.

When we merge units that some kind of object points to, those pointers
might become invalidated, and needs to be updated. Introduce a UnitRef
struct which links up all the unit references, to ensure corrected
references.
At the same time, drop configured_sockets in the Service object, and
replace it by proper UNIT_TRIGGERS resp. UNIT_TRIGGERED_BY dependencies,
which allow us to simplify a lot of code.

Since remote-fs-pre.target is optional we cannot count on it to order
remote mounts after network.target, so let's add that order explicitly
in addition to remote-fs-pre.target.

This hook target enables services to order themselves between
network.target and remote mounts, which is needed for GFS2 and similar
systems.

Explicitly deallocate getty VTs in order to flush scrollback buffer.
Explicitly reset terminals to a defined state before spawning getty.

Instead of the /dev/.run trick we have currently implemented, we decided
to move the early-boot runtime dir to /run.
An existing /var/run directory is bind-mounted to /run. If /var/run is
already a symlink, no action is taken.
An existing /var/lock directory is bind-mounted to /run/lock.
If /var/lock is already a symlink, no action is taken.
To implement the directory vs. symlink logic, we have a:
ConditionPathIsDirectory=
now, which is used in the mount units.
Skipped mount unit in case of symlink:
$ systemctl status var-run.mount
var-run.mount - Runtime Directory
Loaded: loaded (/lib/systemd/system/var-run.mount)
Active: inactive (dead)
start condition failed at Fri, 25 Mar 2011 04:51:41 +0100; 6min ago
Where: /var/run
What: /run
CGroup: name=systemd:/system/var-run.mount
The systemd rpm needs to make sure to add something like:
%pre
mkdir -p -m0755 /run >/dev/null 2>&1 || :
or it needs to be added to filesystem.rpm.
Udev -git already uses /run if that exists, and is writable at bootup.
Otherwise it falls back to the current /dev/.udev.
Dracut and plymouth need to be adopted to switch from /dev/.run to run
too.
Cheers,
Kay

When we kill a process to terminate it make sure to send SIGCONT to
ensure it is unpaused and processes the signal.

We should not handle the ignore list as API mounts, as
systemd itself never touches them.

weaker counterpart of Conflicts=, similar to Wants= vs. Requires=
|
|
The property StopRetroactively= needs to be per-dependency, not
per-unit, in order to properly express dependencies between .mount units
and its .device and fsck .service units. If the .device unit is
unplugged the mount should go away, but if the fsck process terminates
the .mount should stay.

others should be added via .wants/ links
