Bug#652535: debian-edu-config: Default Iceweasel config causes high load and IO when users log in

Package: debian-edu-config
Version: 1.423
Severity: important

The default Iceweasel configuration causes high load and IO when a
user log in.  The problem was reported first at bruker@skolelinux.org, see
<URL: http://comments.gmane.org/gmane.linux.skolelinux.bruker/9251 > and
follow up on
<URL: http://lists.debian.org/debian-edu/2011/01/msg00164.html >.

This causes a thin client server and a main-server to become
unresponsive when a class room of pupils log into the workstations for
the first time.

This is an untested patch that should fix it.  Changelog:

  * Disable browser.safebrowsing.malware.enabled and
    browser.safebrowsing.enabled in Iceweasel, to avoid excessive I/O
    on the home directory server when several users log in.  Based
    on feedback
