I don't have any input into what you should do, so I've trimmed your message
down to what I wanted to respond to.
In regards to my nagios patches causing data corruption, this is the first
time I've heard of it, and I would be very surprised if this was the case, as
I have 5 nagios servers running versions from nagios-1.0b6+chained_hash to
nagios-1.1+chained_hash. In aggregate, they monitor 2476 servers with 9381
services. I have not experienced any data corruption or even had the nagios
daemon crash once. The oldest of the systems has been in production since
3/2003.
If there are any places where the code could corrupt data (or do other
undesirable things), I would like to know about it.
I'm afraid I also have no explanation if Mr. Galstad removed them. (I haven't
been watching 2.0 development, so I wouldn't know if this was the case or not)
Good luck with your coding
