Comment # 2 on bug 1178340 from Neil Rickert

I can comment on the support issue, but ignoring install media issues for now.

The main problem that I see, is that Yast bootloader does not support this
configuration.  If I tell it to use "grub2-efi" then it wants to install the
64-bit EFI version.  Similarly, bootctl (systemd-boot) wants to install 64-bit
booting if I try that.

What I have been doing is using Yast bootloader to install MBR booting, even
though that cannot work.  But at least, if the system is configured for MBR
booting, then "grub.cfg" is properly updated after kernel updates and similar. 
I then install "grub2-i386-efi".  After that, I can use "grub2-install" from
the root command line, and that does install the proper booting for this
system.
