[arm-allstar] logging ideas.. was: update has an error

[Tom Hayward]

I definitely had something more simple in mind, like checking the
return code of processes started by the menu.

Most syslog utilities support log rotation on both size and time. I
haven't looked at which one you use in Hamvoip, but it could probably
be configured with the buffer capability you describe.
