  Oh.  I hadn't thought of that.  Sorry.

  Okay, I'll probably get inspiration from that and my read-only-root
Soekris.  Thanks for the tips.

  As for my problem, I ran a shell loop to "aptitude reinstall $i" on
all installed packages.  It seems to have fixed the problem (or moved it
to an unused part of the card), and I've been able to use the phone as
usual again (not so much as a phone, but as a GPS device to record
traces and enhance Openstreetmap).

Roland.
