What is a safely small filesystem size to use as the root filesystem on an LXD host?
Does it depend on the size of the containers? Does LXD store intermediate archive files on the root filesystem (e.g. in /tmp) when exporting containers or images, or for similar operations?
I’m considering installing Ubuntu 18.04 + snap LXD to a repartitioned Hetzner VPS, as described here: https://blog.simos.info/how-to-repartition-a-hetzner-vps-disk-for-zfs-on-its-own-partition-for-lxd/
Would 4GB be enough for the root partition?
