it was my understanding that LFS was designed for those with only a basic knowledge. personally, if it wasnt for LFS i would have absolutely NO knowledge of linux whatsoever. I think it would be an excellent idea to include the make -j X stuff in the book, since it is for beginners and LFS is a good learning experience, so include all you can ---------------- Colin Kemp GreenBall Enterprises [EMAIL PROTECTED] -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
