That's almost exactly what I did. To be certain, I tried it with the full 
paths you suggest, but of course I got the same result.

As I said the first time, the permissions are the same on both, thus:

# ls -l bin/bash
-rwxr-xr-x 1 root root 772120 2008-05-29 17:29 bin/bash
# ls -l /mnt/rescue/bin/bash
-rwxr-xr-x 1 root root 772120 2008-05-29 17:29 /mnt/rescue/bin/bash

As they're the same size, I assume they're the same version - but they could 
have been compiled with different USE flags. I'll look into that. [Later: 
on remerging bash in the main system the flags look perfectly innocent, and 
I can't imagine having set them differently on the rescue system; but I 
will look next time I boot the rescue system*.]

The permissions are right already, but I'll do that anyway.

I've no difficulty following you :-)

Thanks also to the others who've helped. Wolf's idea wouldn't help me 
because I want a separate system that will boot even if the main one won't. 
It's on a different physical disk as well.

* Is there a way to find out what USE flags a package has been compiled with 
when it's not the current system but a rescue system mounted temporarily in 
it? Anyone?
