原來 m-a 就是協助install module from source package 的tool。
所以package 中一些只有附source的module，都可以用m-a簡單的作buil and install 。
像 qemu 也是..

m-a 是 module-assistant，安裝

aptitude install module-assistant

---

有關 kqemu

kqemu 是close source，所以無法提供 compile 好的package直接安裝。
所以debian 採用source code + obj code的方式 。

需要download source code，重新build成 module。

所以用 module-assistant 來作 get - build - install 的動作
--- 實際上只有build module，還是要手動 modprobe 安裝
