kind of like apt-build world in Debian? (except that that's not guaranteed
to work, because some packages have wrong build-deps...) apt-build puts a
perl wrapper around /usr/bin/gcc to add your -march=athlon-xp
-fomit-frame-pointer -ffast-math -O3 and so on flags when an env var is
set, so packages get built tuned for your machine. (Debian build rules
don't include any provision to compile with -fprofile-gen, run, then
recompile with -fprofile-use, though.)

Debian's supposed to have a package that lets you merge conffile changes
instead of just choosing old or new, look at the diff, or edit by hand. It
doesn't seem be used by default... I haven't read the docs.

Same with Debian testing or unstable.

hehe :) If the shoe fits, wear it. I just wanted to point out that with
some effort, Debian can sort of do the things Gentoo is good at.
