Sounds good. For my own builds, I normally run a host kernel newer
than glibc knows about. I specify --enable-kernel=2.6.33 at the
moment. I prefer it to =current because it reminds me to check what
versions glibc knows about when I build a new system. [ I usually
build several new kernels each month, most of them -rc versions ].
Very rarely, e.g. when I was first messing with kms, I might
specify a slightly older kernel if I think I might have to bisect
But then, I'm usually a firm believer in "run the kernel (on the
host) that you intend to use on the new system". Saves aggravation
trying to sort out an old .config that broke across kernel upgrades -
it's much easier to fix those problems in a full-featured system.
I can see that isn't possible for people using a Live CD, but for
everyone else I still recommend it.
