Comment(by cscott):

 The stanza in olpc-configure is correct; activity directories should not
 be writable.  In the 9.1 timeframe they will be fuse-mounted zip files,
 and definitely not updatable.

 Scratch is broken; it should be using $SUGAR_ACTIVITY_ROOT/data to store
 persistent data, and/or using the Journal interface.

 Workaround in http://dev.laptop.org/~cscott/Scratch-6.xo is to use a small
 wrapper to launch scratch (Scratch.activity/bin/scratch-wrapper):
 {{{
 #!/bin/sh
 # make sure that /tmp/scratch points to the right persistent data
 directory.
 ln -sf $SUGAR_ACTIVITY_ROOT/data /tmp/scratch
 # if they are not already present, copy the examples there.
 if [ ! -d /tmp/scratch/Games ]; then
   cp -ru $SUGAR_BUNDLE_PATH/Projects.skel/* /tmp/scratch/
 fi
 `dirname $0`/scratch-activity
 }}}

 We then move Scratch.activity/Projects to Scratch.activity/Projects.skel
 and replace Scratch.activity.Projects with a symlink to /tmp/scratch.
 Finally, we replace 'exec = scratch-activity' in
 Scratch.activity/activity/activity.info with 'exec = scratch-wrapper'.

 I bumped the version # to 6 after doing this:
