Radix cross Linux

#!/bin/sh
#
# rc.sysvinit   This file provides basic compatibility with SystemV style
#               startup scripts. The SystemV style init system places start/stop
#               scripts for each runlevel into directories such as /etc/rc.d/rc3.d
#               (for runlevel 3) instead of starting them from /etc/rc.d/rc.M.
#               This makes for a lot more init scripts, and a more complicated
#               execution path to follow through if something goes wrong. For
#               this reason, Radix has always used the traditional BSD style
#               init script layout.
#
#               However, many binary packages exist that install SystemV init scripts.
#               With rc.sysvinit in place, most well-written startup scripts will work.
#               This is primarily intended to  support commercial software, though,
#               and probably shouldn't be considered bug free.
