Description of problem:
I tried to perform a manual vnc installation of RHEL-8 in beaker. So I added "manual" keyword to kickstart metadata and vnc to kernel options.

The installation was interrupted with following message:

[  304.396266] anaconda[2171]: An error occurred during reading the kickstart file:                                                          
[  304.396376] anaconda[2171]: One of --drives or --only-use must be specified for ignoredisk command.
[  304.396417] anaconda[2171]: The installer will now terminate.

On RHEL-7 it's completely ignored (or rather not implemented) and does nothing. On RHEL-8 pykickstart enforces the presence of one of two allowed options "--drives ..." or "--only-use ...".

There's a bug 1637872 filed on RHEL-8 where we've suggested to ignore it and log the deprecation message. This would probably solve the problem until RHEL-9.

Can you remove "ignoredisk --interactive" from kickstart if ks_meta=manual is used on RHEL-7 and RHEL-8?

Version-Release number of selected component (if applicable):
Beaker 25.6

How reproducible:
always

Steps to Reproduce:
1. Start RHEL-7 or RHEL-8 installation with ks_meta="manual".
2. Check the generated kickstart for "ignoredisk --interactive".

Actual results:
ks_meta=manual adds "ignoredisk --interactive" to the kickstart even if this is deprecated

Expected results:
"ignoredisk --interactive" is deprecated and shouldn't be used with RHEL-7 or RHEL-8.
