here I manually chose the bootloader target and install completed successfully

The failed attempt tried to install on /dev/sda, which only has 63 free sectors at the start (31.5KB). The successful attempt installed on /dev/sdd, which has 2048 free sectors at the start (1MB).

For mga8, /lib/grub/i386-pc/kernel.img is 47KB. This has grown considerably since mga7, where it is 28KB. So we need to find out why it has grown.

The sync with Fedora in the grub2 package removed the compiler optimisation flag. I've restored that (-Os). That reduced the core.img in my VM from ~30KB to ~27KB, which should be enough.

I believe this was fixed in 8-beta1. Please reopen if I'm wrong.
