I have to ask, since I see a lot of grubby posts (pun intended):
I've *NEVER* run grub2-mkconfig. I've always just yum/dnf update (do
all current updates), or just dnf update kernel (if I wanted to
specifically just do that), and it's always installed the new kernel
properly all by itself. No further action was required by me.
Jonathan Billings:
You should never need to run grub2-mkconfig after each kernel update.
The only reason I can guess at is that they ran it to overwrite the
file in /boot/efi/EFI/fedora/ (which is normally a stub that loads
the default file in /boot/grub2/) and now they have to manually run
it each time.
Normally, the only reason you’d run it is if you changed a variable
in /etc/default/grub. Grubby just creates new bootloaderspec files in
/boot/loader.
Somewhere along the line I removed "rhgb" from there, one way or
another (*), I don't recall ever running grub2-mkconfig, and I've
certainly never run it at every kernel update.
* I don't recall which method I used to remove it from the kernel
command line, but it's not in there, and my system is running fine.
It's the one change I make to booting up Linux, I want to see that it's
actually booting and not jammed. And if it has, I want to see where,
straight away, no horsing around after the fact. Blank bootup screens
are one of the dumbest things about certain other OSs that Linux has
copied.
One other reason for running grub2-mkconfig that I forgot to mention in
my previous email is I also turn off the blscfg functionality in
/etc/default/grub because it doesn't honour all of those settings either.
regards,
Steve
