This would add considerable obfuscation at several points.  The build
process is now designed such that flavours can be added and removed
with minimum fuss.  The resulting packages each provide a working
kernel and modules without further ado.  The d-i can simply offer a
selection of them.

In order to really save space, one should probably turn upon the SMP
flavours.  Unfortunately, I don't have a single processor G5 here, but
I ran some casual tests on a single processor G4 yesterday, and the
overhead from running an SMP kernel did not affect performance
noticeably.  Maybe we should use SMP kernels for d-i as a general
rule, and move the single processor flavours to the second disc.

Regards, Jens.
