Sometimes the simple solution is the best one, sometimes you need something more complex. So whether to use symlinks or a bind mount depends on circumstance.

2008/11/25 Dale [EMAIL PROTECTED]: Could he not share /boot? He may want to have a different set of kernels for some reason but couldn't he even share those? I ask cause I shared when I dual booted Mandrake and Gentoo. Naturally Mandrake didn't last long. LOL It did have different kernels tho. Mandrake used modules like a mad man. Look at the kernel definition line: kernel (hd1,1)/boot/kernel-2.6.27-r4 root=/dev/hdb2 You have to specify a file as a kernel and a / partition. Wherever they are. If you want to share -or not- a unique /boot, feel free. Galevsky

Another reason for having a different partition is that I can easily backup my other personal data to it when I have to format the root partition.

Re: [gentoo-user] Re: dual booting 2 gentoo installations
It looks fine. You can also press e at the Grub prompt or boot to a live cd if it isn't right. -Chris On Mon, Nov 24, 2008 at 5:16 PM, Harry Putnam [EMAIL PROTECTED] wrote: Alan McKinnon [EMAIL PROTECTED] writes: On Monday 24 November 2008 23:04:54 Harry Putnam wrote: I'm just having second doubts about how to dual boot 2 gentoo installations.
