Apparently, though unproven, at 18:03 on Monday 30 August 2010, Paul Hartman

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.
