Re: kernel 3.7.7-201: missing /dev/disk/by-uuid entries; no /dev/disk/by-label
Thanks Kobuck, that was indeed my situation.
I reused a partition from btrfs to xfs and libblkid detected two filesystem signatures, the new one, and the old one (from a backup superblock)
To summarise: if you reformat a partition with another filesystem, recent kernel and libblkid will not try to populate /dev/disk/* if it detects two or more filesystem signatures. If you want to repurpose a partition use wipefs first to eliminate existing signatures.
