Agreed.

Could do. After a discussion on #maemo, it seems something might have
to go in /etc/event.d and I tricked myself into thinking the mount
happened at boot.

This should work as we're not replacing anything with a symlink (the
big problem with upgrading an existing install).

There are two things we probably have to do:

   1) Install /opt/python2.5/lib/... using dpkg.
   2) Move anything left in /usr/lib/python2.5/ manually after install.

Future installs of something like python-hildon will be into the bind
mount, and so go to the right place automatically. maemo-optify will
be updated to not touch anything which depends on Python if we do
this, so Python libraries will continue to install into
/usr/lib/python2.5/site-packages. It's just that this will now be on
the eMMC.

No, I didn't try that. Do you think a symlink should work for that?

Cheers,
