Whomever said this can't be done? :)
I know for a fact that Remenic (#LFS at irc.linuxfromscratch.org) has done
it like that, he didn't feel like installing a distro on his IBM
Thinkpad so he downloading my LFS-2.3.6 i386 static build from
http://quasar.highos.com/ALFS/ (note: most of the stuff here is a couple
of months old, but still usefull....)
He kept that archive on his windows partition, then rebooted and
partitioned+formatted with PartitionMagic, then booted up with Toms'
Bootdisk, got networking going, mounted his new partition, unpacked that
archive and chroot'ed and started the process of installed the rest of
LFS after Chapter 5 (started at Chapter6 instead i mean)
Ok, a bit of hacking in there you have todo, but it's not impossible ;)

Now, for ALFS, there is not going to be a need to have a distro
installed, that's one of the main points.

Dunno, i'm not that familiar with BSD.

Yeah..IE can read XML documents and the profile doesn't have a DTD
(reason it's bitching ;) to parse.

See, bdumm's post (which will problably arrive before mine ;)

I'm talking waywayway in the future here (i was having fun one day on
the mailing lists, just saying how easy it would be todo that on the
fly, without breaking anything when it comes to synchronsation or
You haven't heard how the ALFS IPC system will be in place (well this
hasn't been talked about much, minus a few threads on the mailing lists
and what we talked about on IRC between myself, Gerard and Bryan) which
would make synchronisation on the fly like so, very easy.
The first version i doubt will have much of an interface ;)

It's usually a good idea..

A clean LFS build (with the kernel source tree unpacked in
/usr/src/linux) is just under 200MB, that includes all development stuff
(or aka full LFS build :)
