Description Richard W.M. Jones 2014-10-28 11:41:24 UTC

Description of problem:

systemd/src/kernel-install/90-loaderentry.install

If /proc/cmdline exists but is empty (which apparently is the case
when building live CDs in Koji), then creation of the initrd fails
with:

Could not determine the kernel command line parameters.
Please specify the kernel command line in /etc/kernel/cmdline!

The error is clear enough, but it's not fixable because:

(1) You can't create this file before doing the install in
a kickstart, and

(2) The file would be empty anyway.

Anyway, why is this even a bug?  Just allow the boot options
to be empty.

Here is the full build if you want to take a look:

http://koji.fedoraproject.org/koji/taskinfo?taskID=7959633

Version-Release number of selected component (if applicable):

Fedora 21 buildroot.
For specific versions see the 'root.log' file in
http://koji.fedoraproject.org/koji/taskinfo?taskID=7959633

How reproducible:

100% in F21 and Rawhide.

Steps to Reproduce:

You won't be able to do this unless you've been granted
special koji permissions.  However the command is:
koji spin-livecd --scratch virt-p2v 1.29.2 rawhide x86_64 p2v.ks
or
koji spin-livecd --scratch virt-p2v 1.29.2 f21-build x86_64 p2v.ks

Actual results:

Live CD doesn't boot, because no initrd is created.
