I don't understand why it would be slower. Maybe I'm clueless but I thought
you were moving more towards a single makefile system, kind of like what
BSD had about 15 years ago, you went to /sys/MYMACHINE and typed make and
it did the build completely in that directory. You did different configs
by running a configure tool that made /sys/MYMACHINE /sys/YOURMACHINE, etc.
If this is the general approach, shouldn't this be a lot faster than the
current approach? The current approach stats stuff many times. Linux is
really good at making stats cheap, but nothing is as good as not doing it
twice.
Am I completely misunderstanding what kbuild is all about? My apologies
if so...
