Why do we need to mess with /sbin/init at all?

I like the suggestion that came up here on the list a while back, have
the eselect init module install its own symlink at, say, /sbin/einit.
You would still have to have the user edit their boot loader
configuration file one time if they want to use this, but this makes it
completely opt-in.

The other advantage of this is you don't have to mess with any  init
system ebuilds at all.

This eclass could go away entirely if you don't try to control
/sbin/init.

Keep up the good work; the more simple we can make the integration the
better it will be.
