Talk:Patch webOS Make USB Partition Writable via SFTP
I have found, when setting this up on a brand new phone. That if you use:
cd /media sudo umount /media/internal sudo mount /media/internal
Instead of rebooting the phone, that it disables the camera. It is no longer able to record the images. Other than this issue (which I feel should be included as a warning), the method is sound.
