Yes, I've noticed this too.

I concluded that to the kernel there is something magic about
"init=/bin/someprogram": The program doesn't get PID 1 anymore.

I used to have a script there fire up X and then exec init inside an
Xterm. I gave up on this after that junk started happening.

Oh, and Init refuses to be useful if it doesn't end up with PID 1.
