SMF is the Service Management Facility, the default init system in
Solaris and derivatives since version 10. This adds "smf" to the list
of supported INIT_SYSTEM types, and makes it the default init system on
platforms where it is available.
Packages can introduce SMF support by providing a manifest file, by
default located in ${FILESDIR}/smf/manifest.xml but manifests under
${WRKSRC} can be used too if the package source includes one.
SMF method scripts are supported too if required, using SMF_METHODS in a
similar manner to RCD_SCRIPTS.
Many parts of the SMF infrastructure are configurable, see mk/smf.mk for
the full details.
