dracut/0073-Don-t-create-lots-of-empty-cmdline-files-for-hostonl.patch

From 706f28a7bc193455fcd0656f70adaee442f12ff8 Mon Sep 17 00:00:00 2001
From: Thorsten Behrens <tbehrens@suse.com>

Subject: Don't create lots of empty cmdline files for hostonly-cmdline case

This aligns other places piping cmdline() output to cmdline.d files
with the earlier fix for 95rootfs-block.
