Probably not. It's just something I'm trying. Incidentally, it seems to work OK for me. I'm using Fedora Core 2. Here's my /etc/fstab (only labelled partitions listed): LABEL=dude_root / ext3 defaults 1 1 LABEL=hda_music /home/slimserver/music ext3 defaults 0 0 LABEL=/ /mnt/hda ext3 defaults 1 1 LABEL=/boot /mnt/hda/boot ext3 defaults 1 2 LABEL=/home /mnt/hda/home ext3 defaults 1 2 LABEL=/opt /mnt/hda/opt ext3 defaults 1 2 LABEL=/tmp /mnt/hda/tmp ext3 defaults 1 2 LABEL=/usr /mnt/hda/usr ext3 defaults 1 2 LABEL=/usr/local /mnt/hda/usr/local ext3 defaults 1 2 LABEL=/var /mnt/hda/var ext3 defaults 1 2 And here's what get's mounted: /dev/md0 on / type ext3 (rw) /dev/hda11 on /home/slimserver/music type ext3 (rw) /dev/hda7 on /mnt/hda type ext3 (rw) /dev/hda1 on /mnt/hda/boot type ext3 (rw) /dev/hda3 on /mnt/hda/home type ext3 (rw) /dev/hda5 on /mnt/hda/opt type ext3 (rw) /dev/hda10 on /mnt/hda/tmp type ext3 (rw) /dev/hda2 on /mnt/hda/usr type ext3 (rw) /dev/hda6 on /mnt/hda/usr/local type ext3 (rw) /dev/hda9 on /mnt/hda/var type ext3 (rw) The reason I decided I'd like to use labels is because I found I was spending far too much time trying to find file systems on old disks to copy data across in a new system. Take the example above: /dev/hda is from another system and I wanted to mount all partitions to check some config settings. I found I was doing stuff like: # cat /proc/partitions major minor #blocks name 3 0 120060864 hda 3 1 104391 hda1 3 2 3068415 hda2 3 3 2048287 hda3 3 4 1 hda4 etc. # mkdir /mnt/hda1 ; mount /dev/hda1 /mnt/hda1 # ls /mnt/hda1 (ah, /dev/hda1 must me the old /boot partition) # umount /dev/hda1 etc. Eventually I'd find the root filesystem, mount it, then mount all the other filesystems on the old root fs. With labels I can just do this: # findfs LABEL=hostname_root /dev/hda7 # mount /dev/hda7 /mnt/hda Or even: # mount `findfs LABEL=hostname_root` /mnt/hda Or even; # for d in usr usr/local tmp home var ; do mount `findfs LABEL=hostname_$d` /dev/hda/$d ; done R. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
