Status of Debian Edu "Jessie"

Changes from Wheezy to Jessie

Known problems we must fix

Known problems, we would like to fix

Fixed in git, needs upload to unstable

Known problems, unlikely to be fixed for jessie

Reported problems, not/no longer reproducible

Fixed in unstable (related packages accepted in unstable)

The build-client-opts preseeding in defaults.thin-client-server breaks PXE installs including profile thin-client-server (781515). Fixes addressing this issue have been committed to d-e-config branch 'ltsp-related' and to d-e-install.

After upgrade from wheezy squid should be migrated to squid3 (related fixes have been committed to d-e-config branch 'squid-related'):

Fixed + done (related packages migrated to jessie)

Further ideas

Mostly stuff for Stretch (the release after Jessie)
