Description Jan Stodola 2022-02-01 17:25:30 UTC
Description of problem:
ISO file with an inserted kickstart using mkksiso doesn't have updated kernel command line when the generated ISO is started in KVM:

Later in the installation environment:

[anaconda root@localhost /]# cat /proc/cmdline 
ro inst.stage2=hd:LABEL=RHEL-8-6-0-BaseOS-s390x
[anaconda root@localhost /]#


Content of files on the generated ISO:

[root@s390x-kvm-008 ~]# mount -o loop,ro ks_boot.iso iso/
[root@s390x-kvm-008 ~]# ls iso/
generic.ins  images  sample.ks
[root@s390x-kvm-008 ~]# cat iso/images/cdboot.prm 
ro inst.stage2=hd:LABEL=RHEL-8-6-0-BaseOS-s390x

ro ramdisk_size=40000 cio_ignore=all,!condev
inst.ks=hd:LABEL=RHEL-8-6-0-BaseOS-s390x:/sample.ks 
[root@s390x-kvm-008 ~]#


Version-Release number of selected component (if applicable):
lorax-28.14.64-1.el8

How reproducible:
Always

Steps to Reproduce:
1. see above

Actual results:
Kickstart installation doesn't start, because the kernel cmdline is not updated with the path to the kickstart file.

Expected results:
Installation starts according to the content of the kickstart file.

I think this will fix it:

https://github.com/weldr/lorax/pull/1210

(currently untested though)

Comment 4 Jan Stodola 2022-02-08 07:28:39 UTC
Setting Verified:Tested based on comment 3.

Comment 7 Jan Stodola 2022-02-16 16:53:52 UTC
lorax-28.14.68-1.el8 is included in RHEL-8.6.0-20220215.2.

Moving to VERIFIED.
