Problems with checksum DB

[Jose Subiabre Cabrera]

Hi!
        I want to have control of files changes, so I tried to use the option
checksum=md5 in the file section, something like this:

/tmp/test o=underhell g=underhell checksum=md5 action=warnall

When test file changes, cfengine shows

cfengine:underhell: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
cfengine:underhell: SECURITY ALERT: Checksum for /tmp/test changed!
cfengine:underhell: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Everything ok. The problem is, how I can update checksum DB? Everytime
I run cfagent, it shows me the same message and I only want that 
the warning appears the first time that the file changes. Any suggestion?

Thanks.


PD: Sorry for my english.
