Why does SM need this string? To print it out in the log file?

I want to address a simple need: I need a tool that can
figure out the host name/hca from the GUID, without keeping
a database in some file.

So if I hit the race window while the system is booting, I know
that its booting since the description does not have the format
that I set from userspace, and can simply re-run the tool.

Its good enough for what I want it for, and it seems that no one proposed
anything better so far.

It should be easy to invent some kind of trap for this, but I dont think
anything in the spec matches.
