Release 4.1.1

• Mount user specific binddirs last: Prevously the internal mounts would potentially overwrite user bind mounts [boo#1205011]
• selinux: Relabel shadowed /var files during update to make sure they don't interfere with the update [boo#1205937]
• Clean up /var/lib/overlay more aggressively [boo#1206947]
• tukit: Merge /etc overlay into parent if --discard is used together with --continue - previously the files were incorrectly always merged with the currently running system
• status: do not execute the status command if experimental
• Don't delete created mount point dirs any more
• Small code optimizations
