deployment considerations between STABLE and RELENG

[Jonathan Horne]

its been a while since i have come to the point where i can cvsup and 
buildworld my systems without making any mistakes.  but, at this point, so 
far, i only buildworld up to STABLE.  i do have one dev system that 
yesterday, i finally did a buildworld to RELENG.

as i understand it, STABLE contains all security/bug fixes, as well as all 
enhancements to other applications as they have been developed.  and that 
RELENG contains only security and bugfixes.  have i gathered my information 
correctly?

im interested in polling the users of this list (who frequently buildworld on 
their systems), what situations (deployments) STABLE is for, and the same for 
RELENG.

cheers,
jonathan
