I have added the following line to the /etc/default/grub
GRUB_CMDLINE_LINUX="root=UUID=44***"
run
# grub-mkconfig -o /boot/grub/grub.cfg
and got in the following entry
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Gentoo GNU/Linux' --class gentoo --class gnu-linux --class
gnu --class os $menuentry_id_option 'gnulinux-simple-44***' {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='hd1,msdos3'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos3
--hint-efi=hd1,msdos3 --hint-baremetal=ahci1,msdos3
--hint='hd1,msdos3' 44***
else
search --no-floppy --fs-uuid --set=root 44***
fi
echo 'Loading Linux 4.4.6-gentoo ...'
linux /boot/vmlinuz-4.4.6-gentoo root=/dev/sdb3 ro
}
wich, in my view, does not differ a lot from what was before.
The 44*** denotes the UUID of my boot partition.
Will try it tomorrow and report.
