# init-script for translucency
#
# this script works though a config file and tries to set up translucency
# for each line in this file. comments and whitespaces are ignored.
# The first thing expected in the config is the source separated by some
# blanks/tabs from the target. the line
#
# / /tmp # some comment here
#
# will enable translucency from / to /tmp.
#
# The config-files should be placed in the directory /etc/translucency. The file
# holding the forwards as described above should be named mappings. Two additional
# files, run-up and run-down, may exist holding commands to be executed right
# before translucency is set up (repectively right after translucency has been
# turned off). this may be used to mount a ramdisk used by translucency.
#
# NOTE: this script writes all map-rules from the config-file to /proc,
# even though the maximal number of forwardings is limited in base.h. By default
# only the first eight rules are applied.
