how to keep a freebsd 6.0 release up to date

[Romeo Theriault]

Hi, I'm interested in how to keep a freebsd 6.0 release up to date  
without having to follow the stable branch. All of the security  
advisories have instructions on how to patch systems up to 5.4, even  
though 6.0 is listed as affected also.  I've read that 'freebsd- 
update' will do this, is this correct?   But if I don't want to use  
'freebsd-update' is there a security branch I can follow with CVSup.

Thanks,
