I'm just having second doubts about how to dual boot 2 gentoo installations.
Can I just edit grub from the original install and add the appropriate kernal line like: title=kernel-2.6.27-r3-0x31a-1280x1024 root (hd0,0) kernel /kernel-2.6.27-r3 root=/dev/hda5 vga=0x31A video=vesafb:mtrr,ywrap ## add this for new install title=kernel-2.6.27-r4-0x31a-1280x1024 root (hd1,1) kernel (hd1,1)/boot/kernel-2.6.27-r4 root=/dev/hdb2 vga=0x31A video=vesafb:mtrr,ywrap I didn't want to just try it in case there is something I've forgotten that is likely to get screwed up. I'm not asking if the addressing is right, just asking if in general this can be done with no problems.
