How can I configure the location of the user key store when using the data
protection in mono 2.4 (running apache with mod_mono)?  I believe that the
KeyPairPersistence class is making use of Environment.GetFolderPath
(Environment.SpecialFolder.ApplicationData) so I tried setting the following
in my httpd.conf, but it had no impact.

    SetEnv XDG_CONFIG_DIR /tmp/mono/.config

Instead, mono is still trying to create the user key store in
'/sbin/.config/.mono/keypairs'
Thanks
