# Provide user, group, and mode information for devices.  If a regex matches
# the device name provided by sysfs, use the appropriate user:group and mode
# instead of the default 0:0 660.
#
# Syntax:
# [-]devicename_regex user:group mode [>|=path] [@|$|*cmd args...]
# [-]$varname=regex user:group mode [>|=path] [@|$|*cmd args...]
# [-]subsystem/regex user:group mode [>|=path] [@|$|*cmd args...]
# [-]@major,minor[-minor2] user:group mode [>|=path] [@|$|*cmd args...]
#
# Leading minus in 1st field means "don't stop on this line", otherwise
# search is stopped after the first match.
# default is 0:0 660. user, group can be names (no nss!) or numeric.
#
# =: move, >: move and create a symlink from match to new name
# if lhs is regex: %1..%9 are backrefs to captures
# !: don't create node (but run scripts)
# @|$|*: run $cmd on delete, @cmd on create, *cmd on both AND on change
# cmd also gets $SUBSYSTEM and $MDEV
