Mount a filesystem read-write

출처 : http://android-tricks.blogspot.com/2009/01/mount-filesystem-read-write.html

Very often when you want to write files to a particular partition on ADP1, you will get a "Permission Denied" if the partition is mounted read-only.

To get around this, you need to mount the partition read-write. Typically this is done with /system partition

$ adb shell

$ su

$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts)

/ 를 rw로 하고 싶으면 이렇게 하면 된다.

mount -o rw,remount /
