I mount /dev/hda2 to /usr/local. I EXEC_ONCE a /bin/mount /usr/local in config.ini to mount it for 3rd party apps. You can even use /usr/local/lib for libraries if you append it to the library path before execution. My binaries go into /usr/local/bin. /dev/hda2 gives you 32 megs if I remember right.
Was there not a project started at one time to create a standard install environment for the Empeg? Maybe someday we could re-visit that, especially since new features like site exec have become available in Hijack.
Edit:
here is the thread.
