That is a pretty small item to force a system wide change of OS IMO. You 
could change the source yourself before you push it out.

FBSD 4.6.1 old? What is old? If I had a FBSD 3.5 box still working and 
running under a secure config I would not hesitate to keep it online. I 
currently have one of my mailscanner boxes running FreeBSD 4.8 and one 
running FBSD 5.3. The 4.8 box handles just as much traffic, just as well.
