I think it should be explained somewhere in the LFS book, as an optional feature, the possibility of assigning labels to partitions.
I've recently finished my first LFS build under a virtualbox vm with success. I used two virtual disks: one for the host system and another for LFS. At first I did not used the grub loader installed in the LFS partition, as the host's "update-grub" found the LFS system and everything worked right. But as a final step, I wanted to get rid of all coupling with the host system by removing the host drive. And then I bumped into the real problem: the drive names have changed (i.e. sdb -> sda) and my /etc/fstab was consequently wrong. I did some research to change the default behavior and I found that the labels were the solution. As I think I am not the only one wanting to do this, here is what I think it should be included in the book: The label of an "normal" partition [at least, my ext3 partition used to mount "/"] can be set with: e2label /dev/sdaX LFS_ROOT The label of a swap partition can be set when creating it [I don't know if it can be set after]: mkswap -L LFS_SWAP /dev/sdaY To check what has been done, just execute: blkid And finally, to make fstab label-dependant, edit /etc/fstab and replace /dev/sdaX (and /dev/sdaY) with LABEL=LFS_ROOT (and LABEL=LFS_SWAP). Also, to use Grub with labels [I haven't tested it yet]: http://ubuntuforums.org/showpost.php?p=9585951&postcount=13 -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
