Status of Debian Edu "Buster"

(development started in July 2017)

Installation

A Debian Edu ISO for 64-bit PCs (both AMD and Intel processors) is available from the usual Debian places:

Instead of the default xfce, mate, gnome or kde could be used as value of the related kernel param desktop=xfce. See the Buster manual installation chapter how to set kernel command line parameters.

# Kerberized NFS.
pxeinstall workstation (s).
 - in case installed from cdrom/usb: login as root after first boot
 - run  'sitesummary-client' (needed to be able to use sitesummary2ldapdhcp on the main server). 
Main server:
 - login as root
 - run "ldapvi -ZD '(cn=admin)'" and replace 'sec=sys' with 'sec=krb5i'; the most
  secure setting 'sec=krb5p' works too, but the performance might suffer.
 - run 'sitesummary2ldapdhcp -a'. (default type workstations)
 - as first user edit *new* workstation(s) using GOsa² .
 - don't edit, remove duplicate gateway entry (IP 10.0.0.1 indicates it).

Workstation(s):
 - login as root.
 - run '/usr/share/debian-edu-config/tools/copy-host-keytab'
 - reboot

For systems already configured with GOsa², login on the main server as root and
run /usr/share/debian-edu-config/tools/gosa-modify-host <hostname> <IP>.
Please note: host keytab creation is possible for systems of type workstations, servers and terminals but not for those of type netdevices.

Fixed in Git

Fixed + done (related packages migrated to buster or unstable)

cp /etc/gosa/gosa.conf.orig /etc/gosa/gosa.conf
cat /dev/null > /etc/gosa/gosa.secrets
service apache2 reload

Please note that this change disables gosa-admin password encryption (GOsa² -> LDAP connection); the generated (random) password is used in this case.
