You're right. I forgot, because I always keep a copy of my last .config in
/usr/src which I use when reconfiguring. I never missed it.

I beg to differ. I may not have as much experience as you do, but I've
needed to build a new kernel several times. Under RH5.2 I needed to build
one because support for APM, my Iomega ZIP100 and PCMCIA were not included
in the kernel by default. Now under SuSE 6.1 again I need to build the
kernel because APM, Iomega ZIP100 and PCMCIA are not included. Okay, the
SuSE distro supplies a choice of kernels but none have this *combination*.
And I haven't even mentioned my soundcard...

Above (top), you mentioned this would throw away the .config. This intriges
me I'll have to look at the Makefile tonight and find out the difference
between 'distclean', 'clean' and 'mrproper'.

I've found that with the 2.2.x kernels you can define the 'EXTRAVERSION' in
the Makefile. This allows you to distiguish between kernel builds. Thus you
can create kernels with version 2.2.9-1 and 2.2.9-2 etc. by setting in the
Makefile (4th or 5th line from the top):
EXTRAVERSION = -1
or
EXTRAVERSION = -2
respectively. With these settings, doing 'make modules_install' would place
the modules in the directory /lib/modules/2.2.9-1 or /lib/modules/2.2.9-2
respectively.

I must have misinterpreted things I think I'd better re-read that too ;-)
