Fixed failed Rocky 9 post-install boot with a hack

Some of our older IBM nodes were failing to boot after the image had been deployed. The UEFI PXE boot would fail with this:

UEFI PXE PciRoot (0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/MAC(<MAC>)/IPv4(0.0.0.0,UDP,DHCP,0.0.0.0)

>>Start PXE over IPv4.

After looking at what was present in the EFI partition, I applied this hack of a patch on my rack server and it worked:

Is there a better way to solve this, or would it be a reasonable patch for the project to apply?

Hey, yes I think so. Feel free to send a merge proposal on Launchpad!

Thanks

I’m patching the live code rather than the source code, so I might not get around to the whole process of checking out the repo, testing, etc. Feel free to implement if it’s a good idea.
