A few notes I have:

1. With Jessie and on, with sysvinit /sbin/init //will// be a link,
not the true init file. This would lead to unknowns when the init was
actually sysv.
2. With Upstart, /sbin/init is not a link, so that third test would
give a false positive for sysvinit when it was actually Upstart
(assuming the Upstart check gave a false negative).
3. Maybe you should embed the check for Upstart, so that you do not
have to source all of the init functions, and if that file is ever not
available you still get the correct check.
4. There is a tiny typo in the Upstart check. It needs an extra right
parenthese at the end of the message.
