# Udev rules for device-mapper devices.
#
# These rules create a DM control node in /dev/mapper directory.
# The rules also create nodes named dm-x (x is a number) in /dev
# directory and symlinks to these nodes with names given by
# the actual DM names. Some udev environment variables are set
# for use in later rules:
# DM_NAME - actual DM device's name
# DM_UUID - UUID set for DM device (blank if not specified)
# DM_SUSPENDED - suspended state of DM device (0 or 1)
# DM_UDEV_RULES_VSN - DM udev rules version
#
# These rules cover only basic device-mapper functionality in udev.
#
# Various DM subsystems may contain further subsystem-specific rules
# in 11-dm-<subsystem_name>.rules which should be installed together
# with the DM subsystem and which extend these basic rules.
# For example:
# 11-dm-lvm.rules for LVM subsystem
# 11-dm-mpath.rules for multipath subsystem (since version 0.6.0, recommended!)
#
# Even more specific rules may be required by subsystems so always
# check subsystem's upstream repository for recent set of rules.
# Also, keep in mind that recent rules may also require recent
# subsystem-specific binaries.
