OSNews, Generic OSes Torvalds has indeed chimed in on the micro vs. monolithic kernel debate. Going all 1992, he says: "The whole 'microkernels are simpler' argument is just bull, and it is clearly shown to be bull by the fact that whenever you compare the speed of development of a microkernel and a traditional kernel, the traditional kernel wins. The whole argument that microkernels are somehow 'more secure' or 'more stable' is also total crap. The fact that each individual piece is simple and secure does not make the aggregate either simple or secure. And the argument that you can 'just reload' a failed service and not take the whole system down is equally flawed." My take: While I am not qualified to reply to Linus, there is one thing I want to say: just because it is difficult to program, does not make it the worse design.

Member since:

I'd suggest you do some reading about Linux' CONFIG_MODVERSIONS and what it means before writing such complete nonsense.

"7. Module versioning

Module versioning is enabled by the CONFIG_MODVERSIONS tag.

Module versioning is used as a simple ABI consistency check. The Module
versioning creates a CRC value of the full prototype for an exported symbol and
when a module is loaded/used then the CRC values contained in the kernel are
compared with similar values in the module. If they are not equal then the kernel refuses to load the module.

Fedora is compiled with CONFIG_MODVERSION=y by default, forcing all external modules to be recompiled to match the -exact- kernel version used.
