New Revision: 339413
URL: https://svnweb.freebsd.org/changeset/base/339413
Log:
Move the rc framework out of sbin/init into libexec/rc.
The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
