Yay!  Glad you liked it.

I have most of a Linux From Scratch 6.8 build at

Basically if aboriginal linux's is fed a third hard drive image its init
script will mount it on /mnt and then check for a /mnt/init and run that
instead of a shell prompt. (Note the three second delay if you want to
press a key to get a control prompt, then poke around in /mnt on the
live system.)

The native-build.sh wrapper plugs in a control image and then calls

I note that at one point I built the toolchains (it queries the host to
see what the tuple is, ala "gcc -dumpmachine") but didn't install them
because it would undo the distcc acceleration and the build was slow
enough already. But that's probably a reasonable start?

(Yeah, I should upgrade to the current Linux From Scratch. It's on my
todo list. In the meantime, there's examples of natively building a
gazillion packages, tweaked and tuned to install into aboriginal and
gradually replace most of it...)

It's an option, but newer toolchains shouldn't need most of those
patches. They're for uClibc and cross compiling and such.

If _all_ you want is a fortran compiler, you shouldn't even need to
replace the host toolchain. Just configure for fortran only. Dunno what
kind of libc that might want, not familiar with it myself...

GNU/Linux isn't: Linux=GPLv2, GNU=GPLv3+, they can't share code.
Either it's "mere aggregation", or a license violation.  Pick one.
