Subject: [PATCH] Don't assume that boot commands will only return on fail
While it's true that for most loaders the boot command never returns, it
may be the case that it does. For example the GRUB emulator boot command
calls to systemctl kexec which in turn does an asynchonous call to kexec.
So in this case GRUB will wrongly assume that the boot command fails and
print a "Failed to boot both default and fallback entries" even when the
kexec call later succeeds.
