Bug#930122: Firefox shows black frame when profile rests on NFS volumes

[Mike Gabriel <mike.gabriel@das-netzwerkteam.de>]

Package: debian-edu-config

The observation with a Firefox that has its profile on an NFS share  
is, that when starting the first instance of a Firefox window in a  
session the Firefox process freezes and shows UI elements (frame,  
menus, address bar), but the content area is a black frame for 5-10  
seconds.

This issue can be worked around by setting

  NSS_SDB_USE_CACHE=yes

This should be done in a file in /etc/X11/Xsession.d and /etc/profiles.d:

```
diff --git a/etc/X11/Xsession.d/98debian-edu-config  
b/etc/X11/Xsession.d/98debian-edu-config
new file mode 100644
index 0000000..7c63d5b
--- /dev/null
+++ b/etc/X11/Xsession.d/98debian-edu-config
@@ -0,0 +1 @@
+export NSS_SDB_USE_CACHE="yes"

```

Plus similar for /etc/profiles.d/debian-edu-config.sh
