Re: HURD and Linux on same partition

Hmm, originally sent my reply only to deloptes.

Well, I'm not the OP, but I am somewhat interested more out of curiosity than 
any real intent to try the HURD.

I suspect the following:

   * Libraries (and other software) in source form might be valid / work for 
either kernel, but they have to be compiled for the specific kernel they are to 
be used on, and once in compiled / binary form, they won't work on the other 

   * Is there any way to have libraries compiled for both kernels on the same 
partition -- well, I suppose so (different directories, or maybe even named 
differently?), but the complexity and potential for confusion just wouldn't 
seem worth it to me -- what would be the reason to do that?

On separate partitions, you could boot to a specific kernel (well,  I hope you 
know what I'm trying to say), and then fstab could be adjusted to mount the 
appropriate partitions with the binaries for that kernel / OS.

If anybody can correct / clarify my suspicions, I would be interested.
