5# The normal system boot situation is that init(8) invokes the ramdisk RC
6# script, which invokes the NetBSD rc infrastructure, which in turn calls this
7# script through /etc/rc.d/minixrc.  With a boot ramdisk (x86_ramimage), the
8# ramdisk RC is bypassed altogether, but stored as /etc/rc.ramdisk.  We then
9# have to invoke it here (for startup only!) to let it perform its tasks first.
