Subject: [PATCH] Do not require non-empty kernel cmdline
When booting with Fedora-Server-dvd-x86_64-30-20190411.n.0.iso,
/proc/cmdline is empty (libvirt, qemu host with bios, not sure if that
matters), after installation to disk, anaconda would "crash" in kernel-core
%posttrans, after calling kernel-install, because dracut would fail
with
> Could not determine the kernel command line parameters.
> Please specify the kernel command line in /etc/kernel/cmdline!
I guess it's legitimate, even if unusual, to have no cmdline parameters.
Two changes are done in this patch:
1. do not fail if the cmdline is empty.
2. if /usr/lib/kernel/cmdline or /etc/kernel/cmdline are present, but
empty, ignore /proc/cmdline. If there's explicit configuration to
have empty cmdline, don't ignore it.
(cherry picked from commit 38b4f4b21c3c6107d7a562fcb432237464440b91)
Resolves: #1746069
