#
# In Mint 17:
# Despite the bug report being marked as fixed, the situation is the same. Grub was patched by Ubuntu
# to assign the "ubuntu" distributor ID when it was given "Kubuntu". That results in Kubuntu finally
# getting EFI to work out of the box but still using "ubuntu" as far as grub-install is concerned.
# So we'll stick to "Ubuntu" for this iteration.
