While working through some issues with the ident file for GRUB2 today
with Seth, we noticed that the volsetid file is generated based on the

hostname-<timestamp>

If the primary the aim is uniqueness, would it be preferable to use a
UUID generated py python's UUID implementation?
Or are there other uses it serves such as providing the build host name
as a form of signature?
It originally used the makeuuid command (see 18549 in d.o.o), because in
Python 2.4 there wasn't a uuid object. The only aim here is to ensure
that the root archive mounts the matching CD or USB device when multiple
such devices have media loaded; when it doesn't you get strange failures
due to version mismatches. What's there is unique enough for that
purpose and also somewhat descriptive of the image's provenance.
uuid.uuid1 uses similar basis for generating its uuid's, but isn't
descriptive.
