I have a similar setup: an efi entry for my kernel and gummiboot instead
of grub2.

I would use the firmware boot selector for multibooting, but going there
lengthens the boot by around 10 seconds (Lenovo notebook) which is too
much for my liking.  So instead I by default boot into gummiboot and from
there I choose my kernel, separate grub2's from Fedora and Ubuntu, or
FreeBSD. Everything is nice and fast that way.

Fedora and Ubuntu manage their own grub configs on kernel updates and I
don't have to mess with any boot loader configs myself.

I have a MSI B85-G43 and I must say that thing is the worst when it comes
to managing the UEFI boot order. It completely ignores the one set using
`efibootmgr -o` and instead seems to keep track of the order in which
entries are added.

Half of the time it even ignores me selecting the EFI boot entry during
boot and instead merrily continues to load what it considers to be the
_first_ entry.

So I just use grub2 there and everything is fine.
