I've built CLFS and I'm using it as a guideline and it says how to do it, but not always why, so I'm looking for more information and experimenting to see what works and what breaks. The breaking is very easy. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
