Unknown kernel command line parameters "BOOT_IMAGE=/boot/vmlinuz-5.15.36"

Hello Slackers!

I recently compiled 5.15.36...

I'm using grub in Slack 15.0, this is my /etc/default/grub;

Code:

# If you change this file, run grub-mkconfig -o /boot/grub/grub.cfg
# afterwards to update /boot/grub/grub.cfg.

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=false
GRUB_TIMEOUT=-1
GRUB_DISTRIBUTOR=$( sed 's/Slackware /Slackware-/' /etc/slackware-version )
GRUB_CMDLINE_LINUX_DEFAULT="rootfstype=ext4 scsi_mod.use_blk_mq=1 dm_mod.use_blk_mq=y"
GRUB_DISABLE_OS_PROBER=false
#GRUB_CMDLINE_LINUX=""

# Uncomment to disable graphical terminal (grub-pc only)
GRUB_TERMINAL=console
#GRUB_TERMINAL_OUTPUT=gfxterm

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1920x1080,auto

# sets the kernel bootup console font size.
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_GFXPAYLOAD_LINUX=1920x1080x32

# Font used on the graphical terminal: (Uncomment to use a GRUB_THEME)
#GRUB_FONT=/usr/share/grub/dejavusansmono.pf2

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

#GRUB_PRELOAD_MODULES=all_video

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"
#GRUB_THEME="/boot/grub/themes/vimix/theme.txt"

I noticed in /var/log/messages this line;

Code:

Unknown kernel command line parameters "BOOT_IMAGE=/boot/vmlinuz-5.15.36", will be passed to user space.

I don't ever recal ever seeing an "Unknown kernel command line parameters" message like this in the logs, so I'm not really sure what this is all about?

Anyone?

THANKS

Nothing to worry about. Some of the parameters your Slackware passes to the bootloader are meant for the kernel while others are meant for your initrd.

I had this issue too, and I check it out. I don't remember exactly what it was, but there was a change in the Kernel, and something to do with gcc and grub, which basically made that BOOT_IMAGE line obsolete.

In the end the conclusion is that it is nothing to worry about, it's an obsolete function, so it cannot be read, which is basically what the error says.

Ahh ok, since I'm using Grub, this needs to be an update coming from grub that no longer uses the BOOT_IMAGE line?

THANKS

I don't remember exactly, but I think that was my conclusion too. (I use Grub too as you may have guessed already)

I'm fairly confident you can find the same information if you search that line online and omit the "" and the specific kernel version.

It's my understanding that Grub and Lilo pass this cmd to the kernel...

I know almost nothing about Lilo so I can't say.
