 Note that this is probably not a proper way how to encode a label
 string. I guess that LABEL= option (e.g. from grub.conf) is in human
 readable format (like in /etc/fstab). The mount(8) also supports
 quoted LABELs and UUIDs (e.g. LABEL="foo").

 Currently we don't have a command line util that supports all these
 features, the problem should be fixed in the next util-linux-ng
 release by blkid(8).
