If the message is exactly this (NOT GRANTED by RC), RC is not in softmode,
secure mode instead (in global softmode you would see NOT GRANTED (softmode)
by RC. Add boot parameter rsbac_softmode/ rsbac_softmode_rc to your
grub/lilo to switch in softmode.

I don't remember default values of init, but you could check the default
values of the binaries and the /sbin/init it self together with the boot
role parameters definition to check what's up, the reason of the change you
will found in there.

This is at this way because security concerns, nobody (no daemons, no initrd
scripts etc) should run with boot role, maybe you should create their own
roles to this binaries and make them running under them isolating all you
can.

By default in RC there is inheritance in until a setuid or exec is done if
it's happened then could exist triggers to change the new rol. Check above.

 You should check this too, take a look:
http://www.rsbac.org/documentation/rsbac_handbook/

Furthermore you should add some more information, as which distribution do
you use, version of rsbac and things like this because between others this
parameters by default may change between versions.
