It is also my opinion.
If we are low on entropy, there are several things that can help:
-an "entropy friendly" /dev/?random for "not so important for security"
-a way to use the proper random source based on policy. This means
polyinstantiation support (like the "symlink add RC role" feature
of rsbac. BTW how to achieve this with selinux?).
-a good hot cup of tee.
 At least there is a way to define in the filesystem namespace
object "very important for security". It is commonly called TCB (trusted
computing base), and it is something like the set of trusted binaries,
plus anything they need (libs, devs, etc.)
