Android平板改装成了Debian的系统，有点小问题

[ganhailin]

我卡在chroot和dd上了，前者没有root无法运行，后者不会用，到底怎样吧.tar.bz2直接还原到一个分区下(ext3)？还有，楼主能否共享下具体操作方法？比如到哪里下镜像，挂载等 多谢了。还有，不知楼主那开始段考没，我们这里下周三段考

[oppop007]

这比较麻烦，现在用电视机上的，打字不便。。。。。。等下午或晚上用电脑发个详细的。至于考试，我们这周才考过。。。。怕怕。。。。。

[oppop007]

不一定，android root关键是要破解bootlock这样才可以通过fastboot安装su文件(我记得如此)。
可是据我所知android不用udev的好像，下面只有一个叫uevent的东西(和kernel的uevent有关吗)

这个我倒没听说。不过如果当初编译时允许adbd以root权限启动，而/system挂载的又是支持写入的文件系统(当然，如果是cramfs这类只读的，就只能改固件了)，那么就很容易了！

[oppop007]

(接上)用adb push把su(之后记得设置执行权限)和Superuser.apk复制到相应位置，重启设备即可。至于udev，据本大侠观察，应该是被system_server本身和vold所取代了。

[oppop007]

话说我还在研究用chroot做双系统呢，我用蓝魔v65pro，mips处理器，官方就有root文件系统，但就不知道怎么用，我还是个小白，也是初二，但我五年级时才开始玩linux，不知楼主怎么做到的

（至于如何建立Debian镜像，请各位自行查阅debootstrap的使用说明，本大侠在此不再赘述。）

Tips:
1、To start the pulseaudio server, execute "pulseaudio --resample-method=ffmpeg". You can add this to GNOME's autostart list.
2、If your original system (Android) has some external drivers (modules), remember to copy them into <Debian_root>/lib/modules/<Kernel_version>/...... and execute depmod for better experience.(You can modprobe them easily in the debian terminal when works without Android.)

这里再附几张图，哈哈～

这个比较拉风吧，DosBox！

大家可以搜索
debian android chroot
不够只有英文版，
楼主应该是参照执行的，不错。
那个方法最多缺点就是有个img，电脑上管理要挂载两次，而且chroot本来就有损耗。
另外我的原生方案快成功了，htc evo 3d的。
不过可能先写英文教程。随便宣传一下。

好呀，大家一起加油哦！我有空可以再完善下那堆脚本。当然，也可以帮忙翻译你的教程。

关于chroot的问题，为啥我执行出现can't open /system/bin/sh
还有，我的adb始终是root权限，但终端软件始终是app 但都是井号，是用cat sh > su实现root的

你看看chroot的命令选项说明，让它执行/bin/sh而不是/system/bin/sh。
PS：如果出现command not found的话，再前面加上busybox试试。

（在班上偷偷玩电脑ing……………… ）

[ganhailin]

五一假再说吧，周一至周五不能开电脑，mp4也没有chroot的权限，只能用root explorer进行 remount和修改系统文件，连mount的权限都没有，但它却出个#号来气我。。。。。。
还有，用u盘启动linux系统会不会降低u盘寿命的？因为硬盘没空余分区了，所以才用u盘来装
(这是用mp4上网写的)

[oppop007]

好吧，关于这个问题，改天我详细说明一下。
用u盘启动操作系统的确会降低寿命啊。。。。小心哦！

[ganhailin]

不是你的代码的问题，关键是蓝魔这该死的厂商弄得我无法root，
只好用ln -s /system/bin/sh /system/bin/su
chmod 6755 /system/bin/su
进行root。
不过还是想会考考好些，争取换个真正意义上的平板，至少要能root啊
