# SYNOPSIS
#
#   AX_NAGIOS_GET_INIT
#
# DESCRIPTION
#
#    This macro determines the O/S distribution of the computer it is run on.
#    $init_type will be set and will be one of:
#        unknown (could not be determined)
#        launchd (Mac OS X)
#        bsd     (Slackware Linux)
#        newbsd  (FreeBSD, OpenBSD, NetBSD, Dragonfly, etc)
#        smf10   (Solaris)
#        smf11   (Solaris)
#        systemd (Linux SystemD)
#        gentoo  (Older Gentoo)
#        openrc  (Recent Gentoo and some others)
#        upstart (Older Debian)
#        sysv    (The rest)
