Two quick one for kernel and/or compiler wizards: first, is

Think its 686 (but really, leaving 486 and 586 in isn't going to slow down
booting or anything!) I always say: Use GENERIC unless you have a good reason
not to.
Second, is it safe to do a buildworld with -O3? If there are
No. It's not supported if things break.
stability concerns, I'll go with the default when I rebuild my
6.2 systems.
The defaults should be fine. Also, like I said consider just using GENERIC and
load the odd kmod if needed. Generally it's less headache and equal
performance.
thanks in advance,

Dan,
I know that this has been discussed a few times before, but IMO running a
slightly stripped down kernel (i.e. custom, not GENERIC) actually proves to be
helpful in increasing boot times (if options were added statically) and compile
times if [(# of options added) < (# of options in GENERIC)].
I like being able to compile my kernel on my P4 in less than 10 minutes
anyhow with less options :). The only thing that was brought up earlier
(sometime later last year in a thread--I think either Oct or Nov) is that
removing options removes flexibility as well. But that's a tradeoff you have to
make.
