why are removable storage devices just an adjunct ?

[Mikus Grinbergs]

Applications which I intend to use in the near future I keep 
"resident" (Sugar Activities in /home/olpc/Activities, Linux 
applications on my "permanent" SD card).  Those I access rarely I 
keep on a removable storage device.

Just now was using Journal to access Activity bundles kept on a 
removable storage device.  All I wanted to do was to run them once 
-- but Journal *installed* (in /home/olpc/Activities) each one that 
I clicked on.  I had not expected that.


The XO-1 does not have a lot of nand "storage".  What interests me 
is how best to "off-load" data *and programs* from nand.  I had been 
told that it was possible to run Activities from a removable storage 
device -- but I now see that in the actual implementation it *still* 
requires nand to run an "off-loaded" Activity -- in other words, the 
removable storage device is just an "adjunct", not a "repository".

There really ought to be a better way to "deposit" Activities which 
are not being accessed each week.  Sooner rather than later, there 
simply will not be room in /home/olpc/Activities.
