There's also extlinux of the syslinux project. I'm thinking of giving this a spin on an old system of mine. It's pretty minimalist, doesn't need re- installing after adding a new kernel[1] and it will boot FAT, NTFS, ext2/3/4, Btrfs, XFS, UFS/FFS, so it should cover my needs. [1] I'm used to manually editing /boot/grub/grub.conf with legacy grub anyway, so extlinux is no different. -- Regards, Mick
