In that paper that I mentioned AST talks about how to retrofit modularization to Linux....e.g. adding layers between kernel and drivers to check all comms between them. SELinux comes to mind too. I'm not sure if you can 'modularize' a monolithic kernel like Linux enough to make AST happy. > MINIX predates HURD, surely?

It is more than just fashion. The trend for decades has been that what is too slow in one generation is acceptable in the next. Linus didn't like microkernels cuz they were too slow in 1990s. It seems natural that a decade or so later all of a sudden microkernel performance is acceptable to gain security.
