I certainly can understand this, although I've never tried it yet.

No exactly, you should not run 'make' from the 'init' directory, but rather
tell 'make' where you want it to check for changes :

# make bzImage SUBDIRS=init

It will skip over other directories (such as drivers, fs, net, ...) and
only recompile below 'init'. I do this very often and it's very convenient.
However, you should not do this if you have changed certain compile options
or things that might imply different dependencies.

A hint to check if it has been correctly configured :

# nm vmlinux | grep setuptime
c01b2b80 d __setup_setuptime_setup
c01ab039 d __setup_str_setuptime_setup
c015700c b setuptime
c01b31b0 t setuptime_setup
