That can be done by creating several runlevels, each one having its
set of services enabled with chkconfig. Then in the Grub menu, you can
add one entry per "profile" (i.e. passing the runlevel as a parameter
to the kernel).

Not sure how it can work with Upstart though, and if there is a
maximum number of runlevels that can be created.
