Add a vdev_id feature to map device names based on already defined
udev device links. To increase the odds that vdev_id will run after
the rules it depends on, increase the vdev.rules rule number from 60
to 69. With this change, vdev_id now provides functionality analogous
to zpool_id and zpool_layout, paving the way to retire those tools.
A defined alias takes precedence over a topology-derived name, but the
two naming methods can otherwise coexist. For example, one might name
drives in a JBOD with the sas_direct topology while naming an internal
L2ARC device with an alias.
For example, the following lines in vdev_id.conf will result in the
creation of links /dev/disk/by-vdev/{d1,d2}, each pointing to the same
target as the device link specified in the third field.
# by-vdev
# name fully qualified or base name of device link
alias d1 /dev/disk/by-id/wwn-0x5000c5002de3b9ca
alias d2 wwn-0x5000c5002def789e
Also perform some minor vdev_id cleanup, such as removal of the unused
-s command line option.

In the interest of maintaining only one udev helper to give vdevs user friendly names, the zpool_id and zpool_layout infrastructure is being retired. They are superseded by vdev_id which incorporates all the previous functionality. Documentation for the new vdev_id(8) helper and its configuration file, vdev_id.conf(5), can be found in their respective man pages. Several useful example files are installed under /etc/zfs/. /etc/zfs/vdev_id.conf.alias.example /etc/zfs/vdev_id.conf.multipath.example /etc/zfs/vdev_id.conf.sas_direct.example /etc/zfs/vdev_id.conf.sas_switch.example Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #981

It would be nice to have only one udev helper to handle giving vdevs user friendly names. Currently we have vdev_id and the older zpool_id. This issue is to track incorporating zpool_id functionality into vdev_id so we can retire the former. zpool_id takes input from a file zdev.conf with lines of the form
where
nameis the name to give a disk for which udev's path_id helper producespath. I would like to support a zdev.conf-like syntax in vdev_id.conf, along with a new "topology" type, saytopology explicit. The syntax can't be supported directly, sincenameis an arbitrary string that may conflict with a vdev_id.conf keyword. Therefore I propose a new vdev_id.conf keyword, sayalias, to prefix zdev.conf-like lines, i.e.By default, we would use path_id to generate the string to match. However, to be as generic as possible, we should allow an arbitrary helper to be specified, so users could use names from any of /dev/disk/by-{path,id,uuid,...}
