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
