Wrong output leaks to terminal when making snaphshots

[mzannoni]

When snapshots are automatically made in Majaro update, there is some output appearing in the terminal that doesn't look correct at all:

Removed snapshot: 2026-01-15_21-25-21
------------------------------------------------------------------------------
Detecting snapshots ...

if [ ! -e "${prefix}/grub-btrfs.cfg" ]; then
echo ""
else
submenu 'Manjaro Linux snapshots' {
    configfile "${prefix}/grub-btrfs.cfg"
}
fi
Found 3 snapshot(s)
Unmount /tmp/grub-btrfs.SbgAo6hKI0 .. Success

The above is an example output from one of my latest updates.

This seems to come from:

grub-btrfs/41_snapshots-btrfs

Lines 669 to 677 in 14fa71c

	cat << EOF
	if [ ! -e "${grub_btrfs_search_directory}/grub-btrfs.cfg" ]; then
	echo ""
	else
	submenu '${submenuname}' ${protection_authorized_users}${unrestricted_access_submenu}{
	configfile "${grub_btrfs_search_directory}/grub-btrfs.cfg"
	}
	fi
	EOF

I'd assume this output should be redirected instead?

Discussion already started here.

No, there should be no redirection. The scripts in /etc/grub.d are meant to send to their stdout what should ultimately go in grub.cfg. It is grub-mkconfig to collect all this stuff and send it to the grub.cfg.

Now, what is strange is that if you run sudo grub-mkconfig manually, that bit of script is not leaked to the terminal.

Is it confirmed then that I'm not the only one seeing this?

No, you are not the only one, but the reason for the behavior we are observing is still unclear.
