I'm fairly easy as to the location, though I dont really consider XML
to be humanly readable so I left it out of /etc.

If the file is deleted nothing will change, but next time you reboot, your
bluetooth devices will not be attached and you would have to reconfigure
them. It is not necessary to user edit the entries since the information
comes from the remote device and its not that difficult to get it.

Similarly so with the bthcid.keys file actually - the keys file is created
and maintained by bthcid and should require no user intervention, but it
if its lost then your connections will fail and some user will have to
enter a PIN to authorize a new key.

Is all of /var considered ephemeral or is it just /var/db?  In reality how
likely is it that this will be lost? (do people use mfs for /var?)
