No submenu created on fedora

[diddiman]

I had this working, but one day the submenu was no longer there. Not sure what changed

Not sure what is needed but when i run the snapshots-btrfs i get

 sudo /etc/grub.d/41_snapshots-btrfs

if [ ! -e "${prefix}/grub-btrfs.cfg" ]; then
echo ""
else
submenu 'Fedora Linux snapshots' {
    configfile "${prefix}/grub-btrfs.cfg"
}
fi
Found 12 snapshot(s)
Unmount /tmp/grub-btrfs.83ormpXxcB .. Success

if i the run
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
the generated file has this in the end

### BEGIN /etc/grub.d/41_snapshots-btrfs ###
if [ ! -e "${prefix}/grub-btrfs.cfg" ]; then
echo ""
else
submenu 'Fedora Linux snapshots' {
    configfile "${prefix}/grub-btrfs.cfg"
}
fi
### END /etc/grub.d/41_snapshots-btrfs ###

and the /boot/grub2/grub-btrfs.cfg looks correct with all the snapshots listed. I can also see all the files there, ls gives
fonts grub-btrfs.cfg grub.cfg grubenv

However when i in grub go to the location of grub ((hd1,gpt1)/boot/grub2/), i can see my grub file, but not the grub-btrfs.cfg

Any idea here?

i tried setting
GRUB_BTRFS_GRUB_DIRNAME="/boot/efi/EFI/fedora"
and it worked... Does that make sense? Seemed to be able to boot at least

I'm facing the same issue. Apparently, the prefix variable is set to /usr when 41_snapshots-btrfs is run.
This breaks things because no submenu gets created, as /usr/grub-btrfs.cfg doesn't exist (mine is located in /boot/grub2/grub-btrfs.cfg).

Just out of curiosity, are you also having the same issue?

The prefix variable is set by grub when the script in /etc/grub.d/ are executed, not the 41_snapshots-btrfs-script itself.
If his is set to /usr for you, there went something wrong during grub installation.
