Actually I was wrong, on some boxes with coreutils_8.21-1ubuntu5.4 it
was working fine. This is really an initramfs-tools bug:
https://bugs.launchpad.net/ubuntu/trusty/+source/coreutils/+bug/1535349
I had the version with the fix, but needed to reboot again to get it to
take effect I guess. Rebo
Perhaps it was reverted? This actually works fine for me on trusty in
the older 8.21-1ubuntu5.1 but not the newer 8.21-1ubuntu5.3 or
8.21-1ubuntu5.4 I ran into the problem with it outputting UUID because
amazon's aws ec2 cloudwatch script mon-put-instance-data.pl uses it as
its Filesystem dimensi
