Description Mikhail Krutov 2020-01-13 20:30:20 UTC
My machine requires me to add a kernel parameter to boot:

>acpi_osi=! acpi_osi="Windows 2009" modprobe.blacklist=nouveau

This is due to my optimus video card, which freezes my machine if I don't supply those to grub command line.

In case I supply those to boot live media, the acpi_osi="Windows 2009" parameter gets parsed wrongly: installation program turns it into "acpi_osi=Windows 2009" for resulting grub config.

Steps to reproduce:

1) Boot machine with acpi_osi="Windows 2009" kernel parameter

2) Start installation

Expected result:

Installation program inherits Kernel parameter string exactly the same way it is supplied during boot (acpi_osi="Windows 2009")

Actual result:

Instead, installation program puts in a kernel parameter "acpi_osi=Windows 2009" (notice that the quotes are now surrounding the whole parameter instead of just its value), resulting in unbootable system.

This would be something for linuxrc or installation-images, both of which are now maintained outside the YaST team by snwint@suse.com. Reassigning.
