Bug Description

I'm deploy CentOS on a EFI machine to test the bugfix for [1],[2]. However, what I noticed is that MAAS is not providing the localboot configuration correctly, and instead of providing it for centos, it provides it for Ubuntu.

So this would seem that [1]'s kernel_params.osystem is no longer including the OS System that would allow the template to be rendered correctly.

NOTE: I also modified [2] to hardcode the return of the /efi/centos/grubx64.efi, and the machine successfully booted.

Hi Tony,

It’s not the same issue. Here the local boot config is not evaluating the
OS, where as in the, we are not sending the correct boot loader for centos.
