Sync /etc/default/grub on modification to preserve GRUB_CMDLINE_LINUX workflow Mark grubby as obsoleting grubby-deprecated Be less clever about generating cmdline file from grubby

How do you do these things?

It does not load.

I know the difference between a kernel and grub2. This kernel will not load. Period. Why not?

I tried 3 times --> 5.18.13-200.fc36.x86_64 will NOT load

Kernel will not load. Just hangs at load screen.

• Hard drive does not even click on.

cleared cache each time

dnf clean all --enablerepo=\*

this command:

grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

creates:

• check /etc/kernel/cmdline verify ro rootflags=subvol=root is missing <-- This file

• Previous notes:

Additional info: running grub2-mkconfig /boot/grub2/grub.cfg appears to correct boot entries. If /etc/kernel/cmdline is removed, it appears to regenerate it with double entries for rhgb quiet: ro rootflags=subvol=root rhgb quiet preempt=full rhgb quiet

then lastly

• This only occurs if /etc/kernel/cmdline exists, sorry for not catching that earlier. On a fresh F36 install.
• sudo grub2-mkconfig -o /boot/grub2/grub.cfg

• This creates /etc/kernel/cmdline, it is correct at this point. cat /etc/kernel/cmdline root=UUID=e1b2eceb-4054-4380-8da4-a9a8993a8db5 ro rootflags=subvol=root rhgb quiet

• sudo grubby --args="preempt=full" --update-kernel=ALL cat /etc/kernel/cmdline root=UUID=e1b2eceb-4054-4380-8da4-a9a8993a8db5 rhgb quiet preempt=full

I can load

5.17.5.300.fc36.x86_64

Its not the display manager!

When I try and boot 5.18.13-200.fc36.x86_64 ( OR NEWER) Nothing happens. Like No one is home

Thank you! I hope this gives some more clarity?
