The scratchbox doesn't have this which is perfectly fine as i'll then just fall
back to using $HOME.

But i still have a major problem with this: It doesn't work in the
debian/postinst script when running the application installer.

I simply added a call to "env" to my postinst script to be able to see the
environment bein used in the application installers log. See below the
log i get on my n810. It seems that the worker thread of the app manager that
deals with this has been started before the environment was complete.
So there are no MMC related entries at all which makes this useless to 
install data on the memory card.

So please let me re-phrase my question: How does a postinst script know
where the memory card is?
