It does, but if you do a 'uname -a' - inside or outside the jail -  
you'll see that it reports the OS revision of the host. So you should  
have updated your jails first, then the host ...

One way to get around it is to replace /usr/bin/uname with a shell  
script, which calls the original uname (which you have renamed) and  
pipes through something like sed to replace the revision with what you  
used to have:

#!/bin/sh
/usr/bin/uname.org $* | sed s/"8.0-RC1-p0"/"7.2-RELEASE_p3"/g

And this is a seriously butt ugly hack.
