.SH NAME
|
||||
path_id \- udev callout to provide the shortest possible unique hardware path
|
||||
to a device for the Linux Persistent Device Naming scheme
|
||||
path_id \- udev callout to create a device path based unique name
|
||||
for a device to implement the Linux Persistent Device Naming scheme
|
||||
.SH SYNOPSIS
|
||||
DEVPATH=<devpath>; path_id
|
||||
|
||||
path_id <devpath>
|
||||
.SH "DESCRIPTION"
|
||||
.B path_id
|
||||
is normally called from a udev rule, to provide udev a unique hardware path for
|
||||
a device. Udev can use this information to create symlinks in /dev/ to the real
|
||||
device node.
|
||||
.SH EXAMPLES
|
||||
For all block devices on a system:
|
||||
|
||||
.nf
|
||||
for i in `find /sys/class/block`
|
||||
do
|
||||
DEVPATH="`echo $i | sed -e 's@^/sys\|/dev@@g'`"; path_id
|
||||
done
|
||||
.fi
|
||||
is normally called from a udev rule, to create a unique name, based on
|
||||
the device properties along the chain of parent devices. Udev uses this
|
||||
information to create a persistent symlink to the real device node.
