While preparing to move init(8) to its own package as indicated

While preparing to move init(8) to its own package as indicated
in r339413, a current pkgbase update problem came up.  For users
testing pkgbase at the moment there is no (automatic) way to pick
up new base packages (yet).
As a result rather than also moving init(8) to its own package,
back out the part of the change in r339413 that moved rc* to its
own package and defer creating new packages until the
infrastructure is in place to handle these cases.
Both init and rc* are considered too problematic to be lost by
early adaptors at this stage.
