Except for probably Gentoo, none of the distros really care about bootstrapping systems. I would imagine Gentoo does have some regression test, but I've never looked. Most distros just build packages against the current toolchain, though. >> I can't really think of any simpler way to determine if the >> bootstrapping technique has problems.

Again, though, there isn't really much of a community for bootstrapping systems. I'm guessing that many of the people that care about this are following this discussion. The gsbuild, jhalfs and farce implementations are all using the same techniques, I believe. So, there already is a bit of standardization. Try it for yourself, though. Just read the two do_ica_prep and do_ica_work in gsbuild. I think you'll see that it's pretty unambiguous and that you could easily augment your build platform to do it. http://cvs.diy-linux.org/index.cgi/gsbuild/common-sh.functions?rev=HEAD&content-type=text/vnd.viewcvs-markup -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
