OpenBMC study

1. 如果遇到下面header file找不到__NR_setns的問題，可以把該header file後半部#if 0掉。

/poky/build/tmp/work/x86_64-linux/util-linux-native/2.24.1-r0/util-linux-2.24.1/include/namespace.h


2. 如果想改掉default root's password ('0penBmc')，可以到下面的路徑去做修改。
poky/build/conf/local.conf

3. OpenBMC沒有支援nfs protocol，但可以使用tftp方式把改好的tool/demand丟到/mnt/data (jffs2 rw)或者/(rootfs rw)下面去執行。

4. ipmid是處理IPMI request的main task，透過UNIX socket，聆聽來自/tmp/ipmi_socket的request。

Add some file into /conf

1. Copy the files into "source/sys_defaultcfg-1.0.0-src/data/defaults/etc/defconfig"

or
