With support for SLED11 terminating at the end of March it will be time
for an upgrade to SLED12. Will this work with ZCM preboot services? From
the ZCM documentation I learned that btrfs is out of question, but then
I will be just fine with ext3 or possibly ext4. Will ZCM handle grub2
correctly? Any other things to consider when creating or deploying an
image for SLE12?
