I ran service tor status, and it was definitely dead. What twigged me
was rerunning arm and arm began with running some wizard for "new
site" configuration, so I knew something had gone wrong, checked the
service and sure enough it was "not running".

service tor start and all was back and running within a minute or
less, and arm showed me as much.

So definitely tor stopped running - in a way that was deterministic (I
did run the service tor reload command) but totally unexpected - tor
should never stop running (or crash) with just a config file reload!

DisableDebuggerAttachment 0

This is the only change, the one which subsequent to adding that
option, and running service tor reload, tor apparently stopped
running, as above.

So the only change that I am aware of that could have caused the HSDir
flag (as shown in arm) to go away, was either that option
(DisableDebuggerAttachment 0), or simply the fact that the relay
crashed (or somehow otherwise stopped running).

I am very new to running a relay and still getting up to speed - I
imagine I will be for a while yet, so thanks everyone for your
patience :)
