Mer与xbmc(三)

1. 在Mer的chroot环境下，用开启uxlaunch服务：

        （1.1）直接启动uxlaunch.service服务:

                Running in chroot, ignoring request.

                 【注】chroot环境下好像还是不能启动systemd的服务，原因还不清楚

         （1.2）用uxlaunch命令启动

                  （1.2.1）首先开启一些dbus相关的服务，以及配置一下uxlaunch

                   （1.2.2）uxlaunch

                                       uxlaunch[2228]: uxlaunch v0.64 started.
                                       uxlaunch[2228]: user "root", tty #1, session "XBMC"

【注】从上面的log，目前导致uxlauch启动失败的原因还不清楚
