    snapshot any more.
  - Avoid error message in case a system has no /etc/fstab.sys

- Update to version 2.12

  - Adds easy rollback to last known working snapshot by using "last"
    as the snapshot number
  - Migrate /etc/fstab.sys entires to /etc/fstab for systemd being
    able to create mount units; this will prevent errors on unmount
  - Remove implicit --no-allow-vendor-change - this option can be
    configured in zypper's configuration file now
  - Add support for mounting the /etc overlay file system as a systemd
    unit in /etc/fstab on a read-only system (replacing /etc/fstab.sys
    in the long run)
  - Various bugfixes:
  - Only remove /etc overlays on read-only root file systems
    [boo#1122455]
  - Disable "Persistent" flag in systemd timer unit to prevent
    updates during or immediately after the boot phase
  - Don't set global zypper options during migration - this is not
    supported by the migration plugin
  - Fix error handling when interrupting while rsync is running
  - Filter out security.selinux attributes during rsync

- Use noun phrase in summary.

- Update to version 2.11
  - Update man page to explain new /etc overlay handling

  - Read default update method for systemd service from config file
- Add package "transactional-update-zypp-config" to prevent accidental
  transactional-update uninstallation on transactional systems
  (boo#1111319)
- Use "up" for systemd service on non-rolling release distributions
  (boo#1111321)

- Update to version 2.10
  - Introduce /etc overlays
  - Each root file system snapshot now has a dedicated /etc overlay in
    /var/lib/snapshots/<snapshot number>/etc
  - Changes in older snapshots will be visible in newer snapshots (if
    the file hasn't been changed in both snapshots), but not the other
    way around; this makes it possible to roll back to a previous
    snapshot even if the configuration is broken
  - The /etc state of the oldest active snapshot will be synchronized
    into the new snapshot to prevent ever growing overlays
  - Removed creation of /etc backup snapshots
  - Removed complex overlayfs cleanup handling during dracut early boot;
    only thing left is to output a warning if files have been changed
    in old and new overlay after snapshot creation
  - Unused overlays will be removed during "cleanup" operation
  - Add compatibility with snapper >= 0.7.0
  - Correctly detect BTRFS ID when using multiple snapper configurations

    boo#1097619)

    enforcing or excluding documentation build
