The <blah> is quite important.  If you get the <blah> wrong, the new
binary won't look in the right places for things.  What <blah> did you
actually use?

Well. first rather than copying over, why not copy to /sbin/new-init and
then add to your kernel command-line:

  init=/sbin/new-init

You can then do things like:

  init=/sbin/new-init --verbose

to get detailed output.

Generally speaking yes, provided it was built with the same paths as the
one installed; major version jumps may require matching telinit, etc.
too though

Yes.  Provided you put config files in ${prefix}/etc ... which is not
where the existing /sbin/init was looking for them.


If it's any help, the Ubuntu packages are built with:

  ./configure --prefix=/usr --exec-prefix= --sysconfdir=/etc
--localstatedir=/var/lib

The --sysconfdir is probably the one you're missing - though you should
get prefix and exec-prefix right too
