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.
