五、Meego开发进入MeeGochroot环境
meego-sdk-chroot脚本将设置一个MeeGochroot环境，并给你一个该环境下的shell：
sudomeego-sdk-chroot~/meego-sdk-0524
(用你的chroot目录代替上面的'~/meego-sdk-0524)
注意，这个脚本使用了chroot命令。有些时候，root用户无法在PATH环境变量里定位这个命令(在Fedora里，chroot命令在/usr/sbin路径下)。你可以在meego-sdk-chroot脚本的顶部添加一行alias，以解决这个问题：
aliaschroot='/usr/sbin/chroot'
脚本运行后，会输出下面这样的内容：
1. mount--bind/proc/home/ell/meego-sdk-0524/procmount--bind/sys/home/ell/meego-sdk
2.
3. -0524/sysmount--bind/dev/home/ell/meego-sdk-0524/devmount--bind/dev/pts/home/ell/meego-sdk
4.
5. -0524/dev/ptsmount--bind/tmp/home/ell/meego-sdk-0524/tmpmount--bind/var/lib/dbus/home/ell/meego-sdk
6.
7. -0524/var/lib/dbusmount--bind/var/run/dbus/home/ell/meego-sdk
8.
9. -0524/var/run/dbuscp/etc/resolv.conf/home/ell/meego-sdk
10.
11. -0524/etc/resolv.confroot@meego-netbook-sdk:/#
2.
3. -0524/sysmount--bind/dev/home/ell/meego-sdk-0524/devmount--bind/dev/pts/home/ell/meego-sdk
4.
5. -0524/dev/ptsmount--bind/tmp/home/ell/meego-sdk-0524/tmpmount--bind/var/lib/dbus/home/ell/meego-sdk
6.
7. -0524/var/lib/dbusmount--bind/var/run/dbus/home/ell/meego-sdk
8.
9. -0524/var/run/dbuscp/etc/resolv.conf/home/ell/meego-sdk
10.
11. -0524/etc/resolv.confroot@meego-netbook-sdk:/#
安装其他软件
你可以在chroot环境下正常安装软件(和最新的netbook镜像一样)。
进入chroot环境，然后执行：zypperinstall
下面这个命令可以将整个MeeGo镜像更新到最新版本：
1. zypperdist-upgrade
2.
