Roman probably knows better than I do, but anyway.

AFAICS, "quiet" only means the same thing as the traditional "make
oldconfig", but suppressing questions where the answers are known. (Which
I think is fine)

I was just referring to the following, which really is not in the subtle
change category:

-------------------------------------------------------------
[kai@zephyr linux-2.5.make]$ rm .config
[kai@zephyr linux-2.5.make]$ make
***
*** You have not yet configured your kernel!
***
*** Please run some configurator (e.g. "make oldconfig" or
*** "make menuconfig" or "make xconfig").
***
make: *** [.config] Error 1
-------------------------------------------------------------

whereas lkc changes this to run (the quiet) make oldconfig automatically.

Same thing for

-------------------------------------------------------------
[kai@zephyr linux-2.5.make]$ cp ../config-2.5 .config
[kai@zephyr linux-2.5.make]$ make
make[1]: Entering directory
`/home/kai/src/kernel/v2.5/linux-2.5.make/scripts'
make[1]: Leaving directory
`/home/kai/src/kernel/v2.5/linux-2.5.make/scripts'
***
*** You changed .config w/o running make *config?
*** Please run "make oldconfig"
***
-------------------------------------------------------------

Since people run automated builds, erroring out is IMHO preferable to
dropping into interactive mode, which likely happens when you run make
oldconfig.
