pf and chgrp squid /dev/pf

[dharam paul]

The changes made to the group of squid with the
command' chgrp squid /dev/pf' on freebsd 6.2 is not
permanent. When the system is restarted the groups
revert back to 'root wheel'.
What is the purpose of this command ' chgrp squid
/dev/pf'? Is the change made by it not permanent?

Regards
