Status of Debian Edu "Jessie"

Changes from Wheezy to Jessie

Known problems we must fix

Setting up the LTSP chroot fails, if the netinst or usbstick ISO files are used to set up a combined server in a virtualbox environment (780591).

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)

Fixed + done (related packages migrated to jessie)

Further ideas

Mostly stuff for Stretch (the release after Jessie)
