There is the Appliance 11.4.0 based on SLES11 SP3.
Actually to deploy the appliance I have to install 11.4.1 prereq Update, then 11.4.2 update, then imaging drivers.
And what about SLES11 SP4 ??? No update channels are availiable....

So what sense makes an appliance that is not up to date and cannot be updated in a useful way...?
