New version. Bug fixes and also some new variables exported for UUIDS:
In the future, we may see uuid's which are just simple character
strings (see the DDF Raid Specification). For that reason vol_id now
exports ID_UUID_SAFE, just like ID_LABEL_SAFE. For things like
the creation of symlinks, the *_SAFE values ensure, that no control
or whitespace characters are used in the filename.
(see ChangeLog for a full list of the *_SAFE variables that are now exported).
A quick grep of our rules suggests just one change is needed in 60-persistent-storage.rules where an occurrence of ID_FS_UUID will need to change to ID_FS_UUID_SAFE.
