If you don't care about having documentation of the installed software around on your LFS-system, you can remove it: /usr/share/doc/* and /usr/share/man/* Groet, Thomas -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Thank you Kshitij Jain Things like uclibc and busybox would help http://cross-lfs.org/view/clfs-embedded/ That may go further than you need but should give you an idea -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
