Description Erik Damrose

Created attachment 6074 [details]
Move the configuration of UCRV apache2/startsite to an earlier initscript

Errata 160 introduced a "first steps" site, which is shown on unjoined ec2 instances when accessing http://<ucs>/

There is a timing issue with the original solution. A time window exists when apache is running with the startsite set to the old UMC login.

Solution: Move the configuration of UCRV apache2/startsite to an earlier initscript, before apache2 is started: univention-system-setup-boot-prepare

Patch attached

After this has been fixed, update http://wiki.univention.de/index.php?title=UCS_Appliance#Preparing_Amazon_EC2_Images and remove the workaround.
