I guess the difference is that ubuntu uses an initrd or initramfs, so its initial rootfs is not the ubuntu disk filesystem, and it can load enough of userspace to mount by UUID. For everything *except* the rootfs, mounting by label should probably solve any issues with drives "moving". But for the rootfs itself, mounting by UUID from an initrd or initramfs seems the only reliable way to go. That's supposition, I've never tried to use these and can't remember which of initrd, intramfs is current. I know it's in the BLFS book, but I don't have that in front of me at the moment. I wouldn't attempt to *boot* an LFS system with any sort of external disk connected (hard disk, stick, whatever) because I think the order in which things show up will be random. Probably consistent for one kernel/config, but likely to change for a different kernel or a different config. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
