Slackware and the grub boot loader.

It looks like you're invoking mkinitrd 2 times with different instructions; I'm not sure that will work.

The kernel is referenced in the mkinitrd, and I pass the kernel I want as an argument with -l (so mkinitrd_command_generator.sh -l /boot/vmlinuz-generic).

Also editing the grub.cfg file is not ideal because it is overwritten by grub-mkconfig.

This is the end of the story. Now, what am I doing wrong?

You didn't install the kernel-modules package for the kernel 5.4.50.

I think mkinitrd is using the kernel version you booted with, not the kernel version installed. after chrooting,

Code:

ls /lib/modules

note the kernel version number installed

Code:

mkinitrd -k <version number> -w 10 -m mmc_core:sdhci:cqhci:sdhci-pci:usb-storage:xhci-hcd:mbcache:uas:mmc_block:xhci_pci:ext2

One thing: when I chroot sometimes I'm given a prompt that includes the whole path of the working directory and sometimes it does not include the path. Isn't that weird?

I chroot'ed and ls /lib/modules gave:

Code:

4.4.14 4.4.14-smp 5.4.49-smp

(I installed 5.4.49, not 5.4.50) Should I put -k 5.4.49 or -k 5.4.49-smp?

Not sure, at the moment, do you use the smp on plain kernel? Use one if it doesn’t work use the other one. Which ever one you use, use it with the generic kernel

stf92 · 10-31-2020, 03:02 PM

Regarding my -current installation, which I am using right now, I have found it uses the huge kernel! So it was the huge we finally used for -current, not the generic.

You would need to put in what matches the kernel version. In this case, it would be 5.4.49-smp.

Richard, thanks for a handy little program. I used it to move from LILO to GRUB with no issues. BUT I do have two questions:
1) After following the read.me instructions, should I remove 09_slackware_linux from /etc/grub.d? And then re-run grub-mkconfig once rebooted?
2) I also notice that my Grub menu didn't have the two kernels available in /boot, vmlinuz-generic-4.4.240 and vmlinuz-custom-5.4.75ba. Is it a naming issue? It seems that both are in the grub.cfg under /etc/grub/10_linux, but under a heading for "Advanced options for Slackware-14.2 GNU/Linux" as submenu entries. I'd rather have the latest kernel appear and actually by a default load after 5 seconds of no answer. Is that possible?

Any suggestions would be helpful.
