thanks for the link - as I said I was not aware what the "proper
procedure" is for changing the hostname on my backend

is it pointing out the bleedingly obvious to note that those
instructions appear to be buried deep in a wiki for - what some might
consider an UNRELATED issue of - backing up your database?

maybe it's just me... when I think "change my hostname" I DON'T
immediately associate that with "mysql database maintenance"

even within mthconverg, this "hostname" record is not in a particularly
obvious (for anyone who is familiar with mysql) place that might lead
one to (logically) make the leap from "change my hostname" to "update
mythconverg"

more importantly - really, at the core of the reason this bug was filed
in the first place - the database on 0.25 did not fail so fundamentally
because of this issue, as did the new database on 0.27

thanks again

and now, to create yet another new account in order to get this issue
looked at...

Title:
  cannot expire recordings after upgrade to 0.27

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Invalid

Bug description:
  Noticed my hard drive is filling up - even after I "delete" a
  recording in MythTV no new space is created.

  Looked in the Information Centre and noticed NO new autoexpire jobs
  have deleted any programs since the day I upgraded to 0.27

  Then I saw this in the log:

  $ tail /var/log/mythtv/mythbackend.log

  I changed the hostname on this machine from "loungeroom" to "rem"
  maybe a year or so ago but the hostname is NOT explicitly defined in
  ANY settings (that I have been able to find anywhere?) for mythbackend
  nor mythfrontend

  it would seem somehow this is now having some sort of an effect on
  "mythcorecontext.cpp" - since the upgrade on the 20th of last month. I
  have tried adding "loungeroom" as a hostname for the machine in
  /etc/hosts but that does not help...

  I am fast running out of hard drive space!

  (btw is there some command I need to run to manually clear the backlog
  of programs which need to be deleted?)
