Others have already pointed out the ipkg-link thing, but...I install 
everything on the SD card and have moved /opt, /home/, and /root to SD. 
  This has the side effect of meaning that a reflash does *not* wipe 
everything.  To "recover" after a flash, I had to move a few symlinks 
for /opt, /home, and /root, then reboot.  The process when something 
like this:

     cd /
     tar cf - opt | (cd /mnt/card; tar xvf -)
     mv opt opt.old
     ln -s /mnt/card/opt .

Repeat for each tree and reboot.  Once I did that, all my previously 
installed apps were immediately available.  FWIW, I had to reflash OZ3.2 
because I hosed the /usr/share tree while trying to figure out how the 
incantation to get Opera to display its menubar icons.

HTH,
