When a newly provisioned SuSE node boots for the first time, after the initial installation, the chainload Grub2 EFI from ESP fails (because the grubx64.efi file can't be found).

The SuSE UEFI bootloader can be found at this location:

• SLES:
  ($root)/EFI/sles/grubx64.efi

• OpenSuSE:
  ($root)/EFI/opensuse/grubx64.efi

This problem can be fixed easily by extending the "paths" array within the pxegrub2_chainload template e.g.:

6c6
<   paths = ["fedora", "redhat", "centos", "debian", "ubuntu", "Microsoft", "EFI"]
---
>   paths = ["fedora", "redhat", "centos", "debian", "ubuntu", *"sles"*, *"opensuse"*, "Microsoft", "EFI"]
