Wrong.

Fix vpnc which checks old Maemo file to determine the Maemo-specific configuration way incorrectly - script vpnc-script looks into existence of file /etc/osso_software_version. Unfortunately that script runs each time even vpnc is not started.

BTW, don't try create /etc/osso_software_version - device behavior could change, it is some way to restrict old Maemo versions (application updates).
