An EAL7 general purpose OS isn't likely to happen.
I suppose that depends on the definition of ?general purpose?; back in the dark ages that
was the term that Honeywell associated with SCOMP which managed to achieve TCSEC A1. Of
course the effort routinely broke SRI?s HDM theorem prover used to prove the FTLS and was
generally a royal pain in the ass. If you?re talking EAL7 for something as uber-bloated
as Linux I?d agree with the assertion; it would take a massive rejiggering of the kernel,
hardware with lots of rings (or the moral equivalent) and tools to support formal methods
far better than we have today.
