# init-lib.pl
# Common functions for SYSV-style boot/shutdown sequences.
# These functions assume that under a directory (like /etc/ or /etc/rc.d/)
# there is a directory called rcX.d for each runlevel X. In each runlevel
# directory is a list of files with names like S64foobar or K99smeg, where
# the first letter is S (for commands run at boot time) or K (shutdown time),
# the next 2 digits the execution order and the rest the action name.
#
# Typically, each runlevel file is linked (hard or soft) to a file in
# the directory init.d. Each file in init.d may have several links to it from
# different runlevels (for startup and shutdown). However, some runlevel
# files may not be links at all.
