But from user manual point of view you can not recommend hand written grub first.
I don't have a grub.cfg at hand, but you could add boot options for just one kernel of one install in a similar way to grub.cfg as you could do for syslinux.cfg. [rocketmouse@archlinux ~]$ grep LABEL=s3.archlinux /boot/syslinux/syslinux.cfg | head -3 APPEND root=LABEL=s3.archlinux ro threadirqs APPEND root=LABEL=s3.archlinux ro threadirqs nopti APPEND root=LABEL=s3.archlinux ro If you don't edit grub.cfg manually, you need to configure the auto-thingy configs to add three entries instead of doing it by editing grub.cfg directly. This makes it more complicated and harder to find even a simple spelling mistake.
