Hmm, I feel another software installation Docker learning curve approaching… sounds nice.

So you are suggesting continuing debian 8, install Docker containers and get a debian 9 VM running and migrate my websites/services over and running in the VM, THEN upgrade the underlying debian 8 to 9 once nothing important depends on the old 8 Jessie system…. ? Idea, a project, and more modern and robust. Wouldn’t mind a chance to reorganize/rationalize my disk layouts to mirrored RAID then overlay LVM on top again so adjusting space needs for LV`s is easier.
