2012-01-16unit: reduce heap usage for unit objectsMichal Schmidt
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.
2012-01-14mount: fix quotaMichal Schmidt
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. https://bugzilla.redhat.com/show_bug.cgi?id=773431
2012-01-06unit: properly update references to units which are mergedLennart Poettering
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.

2011-11-01mount: order remote mounts after both network.target and remote-fs-pre.targetLennart Poettering
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. https://bugzilla.redhat.com/show_bug.cgi?id=749940
2011-10-11units: introduce local-fs-pre.target and remote-fs-pre.targetLennart Poettering
This hook target enables services to order themselves between network.target and remote mounts, which is needed for GFS2 and similar systems.

Explicitly disconnect all clients from a VT when a getty starts/finishes (requires TIOCVHANGUP, available in 2.6.29). Explicitly deallocate getty VTs in order to flush scrollback buffer. Explicitly reset terminals to a defined state before spawning getty.

2011-03-28use /run instead of /dev/.runKay Sievers
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.

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

2010-10-29unit: replace StopRetroactively= by BindTo= dependenciesLennart Poettering
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.
