In the SCO UNIX System V/386 3.2 releases, /etc/rc2 is a shell script 
which has been modified to search a series of directories under the 
directory /etc/rc.d. The names of these directories are the numerals 0-9.
These directories are searched in numerical order and any scripts present
will be executed.  All scripts in a given directory will be executed
before moving on to the next directory. Each script invoked will have
the same environment currently inherited by processes invoked from
/etc/inittab.  This configuration (complementary to /etc/rc2.d) is kept
for compatibility with SCO XENIX release 2.3.0 and later.

The classifications of the directories are as follows:
	#  Name			Examples
	0--System init		- time, mnttab, utmp, autoboot
	1--System daemons	- logger, update, cron
	2--Mount filesystems	- mount /u
	3--Crash recovery	- wpsave, expreserve
	4--Clean		- rm /tmp/*, lockfiles
	5--Hardware download	- mtsld, stdld
	6--Kernel software init - net start, mapkey, accounting
	7--User daemons		- lpsched, srvdaemon, netutil start
	8--User definable
	9--System reserved	- bootlog

The mechanism for further subdivision of the rc.d directory is defined as
follows: If it becomes necessary in the future to insert actions between any 
two levels, new directories will be named by appending a decimal point and
one or more trailing digits, for example, 1.1 will be guaranteed to be searched
after 1 and before 2.
