# This file contains the rules to create named MARS devices.

# Although I want to clear the sticky bit explicitly via MODE=, it
# does not work. This seems to be an undocumented feature; I found
# only an changelog entry dealing with the sticky bit, which I did
# not understand. Probably the RUN= can be made simpler.

# The following description is stolen from the DRBD udev rules.
# The rule itself is very different, not stolen.
# DO NOT WRAP THIS LINE
#
# old udev does not understand some of it,
# and would end up skipping only some lines, not the full rule.
# which can cause all sort of trouble with strange-named device nodes
# for completely unrelated devices,
# resulting in unusable network lookback, etc.
#
# in case this is "accidentally" installed on a system with old udev,
# having it as one single line avoids those problems.
#
# DO NOT WRAP THIS LINE
