Hi,
this is an old syslinux menu entry I try to convert to a grub.cfg menu
entry.
$ grep "X .Moon" /boot/syslinux/syslinux.cfg -B1 -A3
LABEL Moonstudio
MENU LABEL Ubuntu X ^Moon Studio lowlatency
LINUX /.boot/ubuntu_moonstudio/boot/vmlinuz-lowlatency
APPEND root=LABEL=moonstudio ro
INITRD /.boot/ubuntu_moonstudio/boot/initrd.img-lowlatency
I don't understand a few things provided by
https://wiki.archlinux.org/title/GRUB#Boot_menu_entry_examples .
The syslinux bootloader, syslinux.cfg and the path
/.boot/ubuntu_moonstudio/boot/ are on a MBR partition with the label
"s3.archlinux", the directories of the other Linux install's root
directory are on a partition with the label "moonstudio".
The new grub2 and grub.cfg are on a GPT partition with the label
"m1.xubu20.04", but this shouldn't matter.
IIUC the grub.cfg entry should read
menuentry "Ubuntu X Moon Studio lowlatency" {
search --no-floppy --set=root --label s3.archlinux
linux /.boot/ubuntu_moonstudio/boot/vmlinuz-lowlatency root=LABEL=moonstudio ro
initrd /.boot/ubuntu_moonstudio/boot/initrd.img-lowlatency
}
OTOH I've got some doubts, should it be vice versa
search --no-floppy --set=root --label moonstudio
linux /.boot/ubuntu_moonstudio/boot/vmlinuz-lowlatency root=LABEL=s3.archlinux ro
should it read root=LABEL or root=label or else?
The fstab of the "Ubuntu X Moon Studio lowlatency" install contains a line to bind mount boot:
/mnt/archlinux/.boot/ubuntu_moonstudio/boot /boot none bind 0 0
Regards,
Ralf
