I'm not paying enough attention to know whether your above fastab works or not, but /dev/disk/by-label/* seems a relatively ugly way of doing things. I'm pretty sure it's not intended that you use that format, and I have no idea whether it's supposed to work that way.

All the guides say to use the word "LABEL". That's not a variable or anything - it's the literal word you're supposed to use.

I have no idea why a guide should be considered unreliable, but the below is not fabricated - it is from an actual working system:

$ grep -ve ^# /etc/fstab

LABEL=boot              /boot           ext2            noauto,noatime  1 2
LABEL=/                 /               ext4            noatime         0 1
LABEL=swap              none            swap            sw              0 0
/dev/cdrom              /mnt/cdrom      auto            noauto,ro,users 0 0

LABEL=space             /mnt/space      ext4            noatime         0 3

shm             /dev/shm        tmpfs           nodev,nosuid,noexec     0 0
$ 

To me this seems cleaner than your format, and it's certainly fewer characters!
