Why is it that chroot semantics in snort change every release? 

I invoke snort like so:

/usr/local/bin/snort -i fxp0 -c /etc/snort/snort.conf -D -o \
  -g 9999 -u 9999 -t /data/log -l /

in 1.7, this worked perfectly.  It put all my logs in /data/log, and the
snort process couldn't see anything else.   Which is almost how I wanted it.

Now, if I specify -t in 1.8, i get the following error:

Initializing rule chains...
ERROR: Unable to open rules file: /etc/snort/snort.conf or /etc/snort//etc/snort/snort.conf
Fatal Error, Quitting..


You're not seriously trying to tell me that I have to put my rules and my
configuration file with my database passwords into the chroot environment
are you?    At that point, why am I chrooting?   Am I the only person who 
wants the program to insulate itself against the possibility of an attacker
compromising it and tampering with the sensor software?
