Does anyone know if there's an easy way to mass-reconfigure mozilla to stick the cache directory in some private subdirectory under /tmp?
An easy way might just be to replace the cache directory with an appropriate symlink to somewhere else.
rm -fr /home/jsmith/.mozilla/default/xxxxxxxx.slt/Cache ln -s /tmp/user-jsmith/mozcache /home/jsmith/.mozilla/default/xxxxxxxx.slt/Cache
Then on the user's desktop create the cache directory under /tmp and set it's ownership and permissions appropriately. It *should* work.
As for the "mass" part, that's what shell scripts are for.
Also, all the pathnames that mozilla uses are burried inside the "prefs.js" file. You can use the URL "about:config" as the safest way to edit those.
