体现了对各个分支的认可。      
I don't think it is better. It's too disordered.      
但是当kernel team的设计思想不一致的时候,走另一个分支比折中妥协高效得多。      
UNIX again?      
我希望linux能采用microkernel的概念.      
I think Linux has been a microkernel OS. Almost all can be made a module.      
Not really.
For microkernel, file system and proccess managment (and etc) are like modules.
Here are just some essential functions in the microkernel.
On this kind of kernel, we can make all embranchments as a modules in function.      
I think microkernel is just a concept. As TCP/IP and OSI, Linux is the TCP/IP, microkernel is the OSI.      
agree
In a manner you are right.
