#
# initscript If this script is intalled as /etc/initscript,
# it is executed by init(8) for every program it
# wants to spawn like this:
#
# /bin/sh /etc/initscript
#
# It can be used to set the default umask and ulimit
# of all processes. By default this script is installed
# as /etc/initscript.sample, so to enable it you must
# rename this script first to /etc/initscript.
