You can comment out 'makeoptions DEBUG=-g' from your kernel config file,
along with all other debugging facilities and set WITHOUT_PROFILE= true in
src.conf. I also have STRIP= -s in my make.conf, but IIRC this should only
apply to ports builds.
The downside to this is if you need to do some serious troubleshooting
you're screwed. On production boxen I run Release versions, and only do
security updates/patches or upgrade to the next Release. In the past using
the most quiescent code has been good to me.
After two kernel builds/installs the huge GENERIC gets moved out of the way.
My i386 box has 91MB of space used in / and the 64 bit boxen are typically
about 93-95MB. I only have one i386 box left and it's crunched down kernel
is 4.2MB, and my 64 bit ones average around 4.5MB.
This can be an effective strategy to mitigate a / being too small, but at
the cost of reducing one's ability to get down and dirty troubleshooting
