gnome-software session service automatically downloads yum metadata, which all goes to the RAM-backed filesystem overlay when running the live image. This is undesired as it can make it difficult to install Workstation on low memory devices. I'd like to fix this by disabling the gnome-software session service when running on the live media, and would like to have a Freeze Exception for F28 Beta. https://lists.fedoraproject.org/archives/list/desktop@lists.fedoraproject.org/message/OXHESICFMAJLYNWZUYXA5TMZMLMBOXTW/

Discussed during the 2018-03-26 blocker review meeting: [1] The decision to classify this bug as an AcceptedFreezeException was made as this obviously causes unnecessary resource usage (especially RAM and bandwidth) during live boots and cannot be fixed with an update.

The PRs to the kickstarts have been merged.
I tested 28_Beta-1.1 compose and the fix seems to work as expected: gnome-software session service doesn't start on the live media and packagekitd doesn't download metadata in the background.
