Title:
  Reverting a previous zsys revert breaks the system: Failed to start
  Network Configuration

Status in zsys package in Ubuntu:
  New

Bug description:
  I've created a virtual machine to assess if zsys is still safe to use
  in Ubuntu 22.04 LTS and I've tried to revert to a previous snapshot.
  So far so good, but once I try to revert the revert it gets
  unbootable: systemd loops between Starting Network Time
  Synchronization and Failed to start Network Configuration.

  Steps to reproduce the behavior:
    1. Revert to a previous snapshot
    2. Revert the revert
    3. See error

  Expected behavior:
    Should revert the revert.

  It's basically a fresh install of Ubuntu 22.04 LTS done following this
  guide: https://openzfs.github.io/openzfs-
  docs/Getting%20Started/Ubuntu/Ubuntu%2022.04%20Root%20on%20ZFS.html#

  I've create a btrfs snapshot of the virtual machine image prior to
  attempting the revert, thus the issue is 100% reproducible on demand.
  I'll be able to keep the VM snapshot around for a couple of weeks
  before having to get rid of it to free up some space. In the meantime
  I'll be able to provide remote access to it if you desire so.
