This update for transactional-update to version 2.14.1 fixes the following issues:

- Improve non-root fs changes checker based on feedback
- Disable snapper's zypper plugin during transactional-update run
- Allow parallel installation with snapper's zypper plugin (useful on read-write systems).
- Warn user if contents of /var have been changed during update
- Swapped position of upperdir and lowerdir in fstab for better readability
- Add hooks for telemetrics
- Fix a serious data loss problem (deleting all files in /etc
overlays) in case /var/lib/overlay/etc is not part of any
snapshot any more.
- Avoid error message in case a system has no /etc/fstab.sys
- Implements support for needs-restart (Fate#326451)
- 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)
- 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
