It can, but as it's not multithreaded, if the database slows down, snort 
will start dropping (i.e. ignoring, rather than blocking) traffic.

No. Snort logs to a unified log file, barnyard picks up new entries and 
sends them to the database server. The database server and barnyard can be 
on the same host, or different hosts. Barnyard and Snort must be on the 
same machine (unless you use NFS or something to share out the log 
director... ewwww...)

To return to your original problem, though, what user is attempting to 
start snort at system boot? Do they have read access to all the snort 
config files? What error messages are given? (they might be in 
/var/log/messages or similar).
