I didn't want to get in on the discussion, but for me every time you need to recompile software to get to feature A, I consider it a bug. Rebooting to enable a feature? Sure. Recompiling software to enable a feature? What? Is this the middle ages? What happened to shipping software/binaries that can work for everybody? The way I see it, profiling currently works for *both*, users that need the libs and users that don't need the libs. Reducing compile times is not a worthy goal, IMHO, as no user should ever have need to re-compile FreeBSD. Neither to tune something in GENERIC nor to rebuild world. Just my 2 cents, Uli
