From skolelinux to debian-edu, upgrade of debian-edu-config dangerous

[Petter Reinholdtsen <pere@hungry.com>]

To make sure we have a consistent naming of all configuration files
and scripts, I am renaming the instances of 'skolelinux' to
'debian-edu' in the next version of debian-edu-config and
debian-edu-install.

I have to do it now, as it will be impossible to do it after we
release the stable version of skolelinux.

Upgrading to debian-edu-config version 0.380 might break your existing
installation!  It _might_ work to run cfengine-debian-edu after the
upgrade to fix this problem, but this will also disable all local
configuration changes.  Upgrading debian-edu-install should not have
any effect on running installations.

These are (most of) the affected configuration files.  I hope I got
them all.

  /etc/X11/Xsession-skolelinux
  /etc/X11/Xsession.d/10skolelinux-one-login-per-host
  /etc/X11/Xsession.d/10skolelinux-set-umask
  /etc/X11/Xsession.d/20xfree86-skolelinux_kdedirs
  /etc/courier/authldaprc-skolelinux
  /etc/cups/cupsd-skolelinux.conf
  /etc/dhcp3/dhcpd-skolelinux.conf
  /etc/dhcpd-skolelinux.conf
  /etc/ldap/slapd-skolelinux.conf
  /etc/pam.d/cron-skolelinux
  /etc/pam.d/cupsys-skolelinux
  /etc/pam.d/kde-skolelinux
  /etc/pam.d/kscreensaver-skolelinux
  /etc/pam.d/login-skolelinux
  /etc/pam.d/other-skolelinux
  /etc/pam.d/passwd-skolelinux
  /etc/pam.d/passwd-skolelinux2
  /etc/pam.d/samba-skolelinux
  /etc/pam.d/ssh-skolelinux
  /etc/pam.d/su-skolelinux
  /etc/samba/smb-skolelinux.conf

The most likely local changes are in dhcpd-skolelinux.conf, as the
others should not normaly need local modifications.
