Further reading shows that the original issues with a symlink /etc/mtab were resolved in late 2009 (loop mounts, nfs, user=options), and LFS originally had a symlink for /etc/mtab way back in at least 3.x days Given that Debian, Fedora, and possibly Ubuntu (have not checked a recent dist) all now use a symlink, should we change to also doing that? The only changes we might need to make are the bootscripts may need to add a -n option to all mount commands to suppress any update errors - unless util-linux has fixed mount recently to no longer attempt to write to a symlinked /etc/mtab.... (oh, and the policy rant referred to the /usr split warning rather than /etc/mtab - the place for that warning is in the documentation and build time, not runtime...) -- -- - Steve Crosby -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
