This syntax never worked here. Always resulted in
an unbootable system.
Only the /dev/disk/by-label/ syntax works reliably.
Afaik if you are using GRUB LEGACY (0.97) and want to
use LABEL/UUID in
your grub.conf/menu.lst you also need an initrd. I
think with GRUB 2
(1.98) it is possible without. You don't need an
initrd for LABEL/UUID
in /etc/fstab for both cases.
FWIW I'm using sys-boot/grub-0.97-r10 with GPT, labeled
partitions and
no initrd. My kernel has EFI_PARTITION compiled in (no
module).
My fstab looks like this:
LABEL=swap none swap sw
0 0
LABEL=boot /boot ext2 defaults,noatime
1 2
LABEL=root / ext4 defaults,noatime
0 1
LABEL=home /home ext4 defaults,noatime 0 1
My kernel boot commandline still specified root by device name
/dev/sda2 but otherwise my system works normally so far. :)
Don't listen to nay-sayers. Your fstab will work just fine and
there's nothing
wrong with it.
The LABEL= sysntax has also worked for years and years now on
all grub-
supported filesystems that support volume labels. I don't know
where a
previous poster got the idea from that it is not supported, or
you need an
initrd - I have never used an initrd on Gentoo and have used
that syntax since
forever.
Similar for claims of unreliability by someone else. The only
cause I can
think of is using weird grub patches or some combination of
insane flags.
So I don't have to have the complete path in fstab like this:
/dev/disk/by-label/boot /boot ext2 noatime
1 2
/dev/disk/by-label/root / reiserfs defaults 0 1
/dev/disk/by-label/swap none swap sw 0 0
/dev/disk/by-label/portage /usr/portage ext3 defaults
0 1
/dev/disk/by-label/home /home reiserfs defaults
1 1
Can you post a grub.conf file that uses labels? Sort of a example
to look at and go by.
Dale, there are two examples of fstabs in this message (actually
three). But you only want to see those you didn't write. You just need
to put "LABEL=somelabel" in the first column.

That's what I wanted to clarify. I put the whole path but others
didn't. I wasn't sure if they meant that literally or if they just
shortened it a bit. It looks like it will work either way.
