I’m currently running a good chunk of my ubuntu systems on ZFS – based off of the ‘official’ ZOL guide. It uses a small EFI partition for Grub, and has a pool for boot. It works better for some of my use cases, and I’m happy with it. There’s a recent discussion of dropping several filesystem types for /boot on Ubuntu on the Ubuntu Community Discourse.
On the short term, I should be fine cause I run my boxen on the current LTS at the time I’m building them then upgrade.
However at some point, the potential for breakage on a system upgrade may pop up.
So… As a Root on ZFS user, how likely is this to break my existing setups on upgrade?
