Hi,

Following the above advice I would use the following cvsup file:

*default host=*Insert CVSup mirror here*
*default base=/usr
*default prefix=/usr
*default release=cvs tag=RELENG_4_3
*default delete use-rel-suffix
*default compress
src-all

This will fetch the source for 4.3-RELEASE + security fixes, (for the 
release I think the tag is RELENG_4_3_0).

Do the normal make buildworld & kernel dance as documented in UPDATING 
and the handbook.  Then repeat the whole process with RELENG_4_6 as the 
tag and then again with RELENG_4_8 (and RELENG_4_9 if you want 4.9 
release).  This will take some time especially if your machine is slow 
at building.  It might be worth verifying each step works by running 
with it for a day or two before going onto the next step.  Also be sure 
to have good backups.  Having said that I do builds all the time and 
have never had a significant problem.
