Thank you for your reply,
I do wanted to show you this: snapd
Looking at that github page shows there's currently no 'stable' more-then-long-supported distro supported by snapd.
I understand that this is because snapd is very new and thus may require new techniques, but I believe you'll also understand me if I say I want my servers to be able to run for ~5 years without me having to reconfigure/replace them.
But for now I'm thinking about testing Fedora with the LXD snap because that fits the best within my server environment because I do really love the work everyone from LXD has done to improve LXC.
Again, thank you for your help,
