Syntax error in grub.cfg.

Hi:
Code:
root@revenge grub.d]# cat /etc/grub.d/40_custom 
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

echo "Adding Slackware-current." >&2
cat << EOF
menuentry "Slackware-current" {
set root=(hd0,3)
linux /mnt/boot/vmlinuz-generic root=/dev/mmcblk0p3 ro quiet splash
initrd  /mnt/boot/initrd.gz
}
EOF
[root@revenge grub.d]#
Where is the syntax error. grub-mkconfig -o /boot/grub/grub.cfg reports it. The command was
Code:
[root@revenge grub]# grub-mkconfig -o /boot/grub/grub.cfg

why are you using a custom file for slackwhere, grub doe not pick it up on its own?
do you have one of them laptops that has their "hdd" as a sd card setup, or are you using a SD Card plugged into your laptop SD Card Slot?

for current as it is right now grub shows it as slackwear 14.2+ for current.

cat << EOF and EOF does not belong in there

Change the file to just this:

Code:
menuentry "Slackware-current" {
set root=(hd0,3)
linux /mnt/boot/vmlinuz-generic root=/dev/mmcblk0p3 ro quiet splash
initrd  /mnt/boot/initrd.gz
}
Also, is /mnt/boot correct?

It seems to have a problem with initrd.

Yes, it has an eMMC device instead of a hard disk.

You see?, the os-prober puts the huge kernel, but I want the generic one to be booted!

No, I think it is not. Thanks for the warning.

you need to preform these steps to get your kernel changed over first. Then just updating grub should do the trick.

https://docs.slackware.com/slackware:beginners_guide

your sub menu
Code:
submenu 'Advanced options for Slackware 14.2 (pre-15.0 -current) (on /dev/mmcblk0p3)' $menuentry_id_option 'osprober-gnulinux-advanced-ca12f07c-07c7-4c0a-a9c1-597b0d7020f0' {
	menuentry 'Slackware 14.2 (pre-15.0 -current) (on /dev/mmcblk0p3)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-/boot/vmlinuz-generic-4.14.34--ca12f07c-07c7-4c0a-a9c1-597b0d7020f0' {
		insmod part_msdos
		insmod ext2
		if [ x$feature_platform_search_hint = xy ]; then
		  search --no-floppy --fs-uuid --set=root  ca12f07c-07c7-4c0a-a9c1-597b0d7020f0
		else
		  search --no-floppy --fs-uuid --set=root ca12f07c-07c7-4c0a-a9c1-597b0d7020f0
		fi
		linux /boot/vmlinuz-generic-4.14.34 root=/dev/mmcblk0p3
But I'd still follow the steps in slack.docs

You say that's the submenu I should use? But where is the initrd line? Anyway, I erased the /mnt element from the path and ran grub-mkconfig, booted and the following happened:
Code:
/boot/initrd.gz: Loading kernel modules from initrd image:
insmod  /lib/modules/blah/blah
insmod /lib/modules/blah/blah
mount: can't find /mnt in /etc/fstab
ERROR: No /sbin/init found on rootdev (or not mounted). Trouble ahead.
I mount could not mount whatever it was then the error following makes sense (not mounted). The question is where does /mnt come from. Any file containing that word? I search the string 'mnt' in /boot/grub/grub.cfg and did not find it.

I will run the mkinitrd-command-generator and see what happens.

the custom file is made by the user, so you tell me where did you get the /mnt/
linux /boot/vmlinuz-generic-4.14.34 root=/dev/mmcblk0p3

I do not know the file structure for this type, but go to that link and read the instructions to change your kernel, but you have to boot in using your hudge then do the work when when you're finished then do not do the LiLo step, update grub instead.

You see?, the os-prober puts the huge kernel, but I want the generic one to be booted!
Give https://github.com/Richard-Cranium/SlackwareGrub2 a try. Post if it works or not. (For example, it will attempt to match up files vmlinuz-generic-4.4.132 and initrd-4.4.132.gz first.)

It should be this.

Code:
menuentry "Slackware-current" {
set root=(hd0,3)
linux /boot/vmlinuz-generic root=/dev/mmcblk0p3 ro quiet splash
initrd  /boot/initrd.gz
}

Either with my 40_custom or with Richard Cranium's file I get the same errors:
Code:
mbcache: export duplicate syjbol _mb_cache_entry_free (owned by kernel)
modprobe: ERROR: could not insert 'mb_cache': Exec format error
[Idem]
modprobe: ERROR: could not insert 'ext2': Exec format error
mmc0: new HS200 MMC card at address 0001
mount: mounting /dev/mmcblk0p3 on /mnt failed: No such file or directory
ERROR: No  /sbin/init found on rootdev (or not mounted). Trouble ahead.
Notice the slackware installer reads/writes the eMMC memory perfectly well. So in principle the drivers to access that device are there. By doing mkinitrd_command_generator.sh the driver for mmc (I forgot the name) appeared. So this was a great step forward in the road to boot Slackware on this machine. Now perhaps /dev/mmcblk0p3 should be named by the long name given by blkid.

Those errors indicate that you are still using the HUGE kernel instead of the generic kernel. The error is harmless by the way. It's what happens if you 'modprobe' a module which is already built into the kernel.
Since you are using "/boot/vmlinuz-generic" in your grub configuration, which is a symlink, it is probably pointing to the huge kernel.

You should always use the full name of the generic kernel and not rely on a symlink which is only there for newbies and to make unattended (huge) kernel installs and upgrades possible.

Well, there are two things I don't understand here. This is the latest grub.cfg I have used, which produced the errors shown above (post #):

Why did grub-mkconfig not include this stanza? Second question. In the grub.cfg file there are a lot of menues and submenues for slackware in the os_prober section. Two of them have the words vmlinuz which is a symlink pointing to the huge kernel. And the submenu where it puts 'vmlinuz-generic' it does not include the initrd file!!!

In short: I need to know what the 09_slackware_linux file has that makes grub-mkinstall not to include it in grub.cfg. On the other hand, the vmlinuz-generic link is pointing to the generic kernel, as I have just checked.

EDIT: I have just edited by hand the grub.cfg file, replacing 'vmlinuz' by 'vmlinuz-generic' in the first submenu. The second submenu I don't care right now as it is the Advanced Options option when one boots. Result: no more errors due to modprobe but still it does not find /dev/mmcblk0p3. I'll replace this by the uuid number provided by blkid and see what happens.
