Das macht ohne udev Regeln keinen Sinn, da ja auch die Kontroll-Node
jedesmal neu erstellt weden muss.


(auszug aus /etc/udev/rules.d/10-dm.rules)
....
# 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

KERNEL=="device-mapper", NAME="mapper/control"

SUBSYSTEM!="block", GOTO="dm_end"

# Device created, major and minor number assigned - "add" event generated.
# Table loaded - no event generated.
