Adding (undetected Linux) boot menu entries to Open Core text menu without config.plist.

[mek21]

Works with Open Core 0.9.9 release.

 

Under linux boot directory create folder named "loader",

Within "loader" directory create subfolder named "entries",

 

Within subfolder "entries" create a .conf text file and name it with the name of the kernel you intend to boot,
example: vmlinux-6.7.0.conf

 

Inside the .conf file choose a title for your linux menu entry, specify the path to linux kernel and initrd entries, kernel options and root UUID of your distro (get UUID using linux "lsblk -f" or "sudo blkid"),
example:
title Ubuntu
linux    /boot/vmlinuz-6.7.0-rc1
initrd    /boot/initrd.img-6.7.0-rc1
options root=UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx ro
