Re: Rebuilding cf_lastseen.db

[Chip Seraphine]

Wow, you nailed it.  You must have, like, ESPN or something.

Apparently version 3.3 creates a db-3.3.a but not a db.a, so when I 
copied over the 4.2 archive files in my build lib directory I did not 
stomp on  one.   Serves me right.

It occurred to me about 1 ohnosecond after sending the email that if 
cfengine couldn't handle a missing cf_lastseen.db then the thing would 
have never installed in the first place.  Something about hitting 
'transmit' that causes insight to flare up a second or two later....
