Boot with the "noeject" option. This is documented in the

If /cdrom or /KNOPPIX are not mounted, init will not ask for a key
to be pressed, just like in the installed version. Please have a look
into the source code. You can still exchange init with your own version
(which will probably be unable to eject the CD, on the other hand), or
don't call init at all and do an immediate reboot instead, by invoking
the appropriate system call.

Yes, if the patch makes sense and is compatible with standard init.
