Bind one directory to another I would like to bind one directory to another in order to extend the storage capacity of the first directory.

In linux you can execute:

mount --bind /path/to/directory1 /path/to/directory2


However, the Android shell doesn't understand the "--bind" and "-B" params.  This could also be accomplished through fstab, but I'm unsure of the syntax.

I need to perform this operation because my Samsung Galaxy S (SGS) has /data/data symlinked to /datadata, the latter of which resides on a partition that can only be 115 MB, and is constantly full as a result. I'd like to extend the space by binding a directory from somewhere else with more room.

Thanks in advance, I've been looking around for two days for some ideas.

  Do you have busybox installed? Have you tried mount -o bind /path/to/dir1 /path/to/dir2 (I think the busybox version supports that on Android)?
