604f104af4 if a node goes away, possibly restore a waiting symlink 2007-03-19 11:57:54 +01:00

24f0605c1f priority based symlink handling
Symlinks can have priorities now, the priority is assigned to the device
and specified with OPTIONS="link_priority=100". Devices with higher
priorities overwrite the symlinks of devices with lower priorities.
If the device, that currently owns the link goes away, the symlink
will be removed, and recreated, pointing to the next device with the
highest actual priority.

This should solve the issue, that inserting an USB-stick may overwrite the
/dev/disk/by-id/-link of another disk, and removes the entire link after the
USB-stick is disconnected. If no priorities are specified, the new link will
overwrite the current one, and if the device goes away, it will restore
the old link. It should be possible to assign lower priorities to removable
devices, if needed.

In multipath setups, we see several devices, which all connect to the same
volume, and therefore all try to create the same metadata-links. The
different path-devices are combined into one device-mapper device, which also
contains the same metadata. It should be possible, to assign multipath-table
device-mapper devices a higher priority, so path-devices that appear and
disappear, will not overwrite or delete the device-mapper device links.

95776dc6ec consistent key naming to match only the event device or include all parent devices
This scheme is more consistent and makes it obvious if a match happens
against the event device only, or the full chain of parent devices.

The old key names are now:
  BUS -> SUBSYSTEMS
  ID -> KERNELS
  SYSFS -> ATTRS
  DRIVER -> DRIVERS

Match keys for the event device:
  KERNEL
  SUBSYSTEM
  ATTR
  DRIVER (in a future release, for now the same as DRIVERS)

Match keys for all devices along the parent device chain:
  KERNELS
  SUBSYSTEMS
  ATTRS
  DRIVERS

ID, BUS, SYSFS are no longer mentioned in the man page but still work.
DRIVER must be converted to DRIVERS to match the new scheme. For now,
an error is logged, if DRIVER is used. In a future release, the DRIVER
key behaviour will change.

fa33d857e2 don't remove symlinks if they are already there
Consecutive "add" events will not remove and recreate the same symlinks
anymore. No longer valid links, like after changing a filesystem label,
will still be removed.

ff9a488d8c remove old symlinks before creating current ones
This will prevent incorrect symlinks when a filesystem
label is changed and the event is triggered again from
sysfs.
