Re: [ug-bjosug] 请问：solaris是不是微核心操作系统？

[Chen Jerry]

According to Monolithic Kernel Versus Microkernel Designs from Chapter
One of  Linux Kernel Development,
Linux is monolithic and modular.
Windows NT and Mach are microkernel, but all servers run in kernel
space defeating the primary purpose of microkenel designs.

I suppose Solaris has been taking the pragmatic way as well. As Joey
said, it's yes or no:-)

Am I right?
