Thanks for your suggestion! Actually, zsys does it a little bit differently: - snapshots (state save) are taken everytime you modify your system by apt or other things. - In addition to this, everytime you reach graphical.target, we stamp the current state (which can also be a clone) as the latest good known boot status
Thanks to both of those information, you can revert in grub to any state changes and you can also revert to a clone (which is a revert of revert, basically), this is why we don’t need explicitly additional state saved on boot. However, you still can take your snapshots automatically, like with this service files, but just some suggestions: - You shouldn’t consider a successful boot to be Before=zfs-mount.service. As you don’t know yet if the system completely boot or not. Also, this has the side-effect of delaying your boot. You should be After default.target (which is a symlink to graphical.target on desktop) - You don’t need to be After=zsysd.service. Zsys is socket actived, and you can rely on only its socket to be present. - I suggest you only run zsysctl save without any argument or a least prepending its name with autozsys_, so that those are garbage collected automatically by our system, you will have to clean them up manually. I’m thus marking the bug as Invalid as the design doesn’t need it, but as said, nothing prevent from people running this. I think we can even put that on a wiki in the github project (https://github.com/ubuntu/zsys): are you interested in crafting this page with the above information?
