Devmon operates from the hosts.db file. If changes have been made to bb-hosts, 
devmon needs to be run with the --readbbhosts option to update the hosts.db 
file. It may be convenient to automate this. All of this is covered in the 
docs (INSTALLATION).

No.

If the file does not exist, devmon would require write access to /var/log to 
create the file. I typically run devmon as the 'devmon' user, and configure 
it to log to /var/log/devmon/devmon.log, and create /var/log/devmon such that 
the 'devmon' user has write access to /var/log/devmon.

You mean you are running devmon with the --readbbhosts option according to 
item 5 in INSTALLATION ?

You can run devmon with --readbbhosts --debug to get more information.
