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.
