Description of problem:

On my system, /bin and /sbin are symlinks to /usr/bin and /usr/sbin. This is done by installing the usrmerge package. I suppose this is the same mechanism in Fedora after UsrMove.

So, I have:

lrwxrwxrwx 1 root root 7 sept. 27 15:07 /bin -> usr/bin
lrwxrwxrwx 1 root root 8 sept. 27 15:07 /sbin -> usr/sbin

It seems that supermin isn't able to work with such a layout.

Version-Release number of selected component (if applicable):

supermin 5.1.16-1 (from Debian Unstable)

How reproducible:

Always

Steps to Reproduce:
1. Install usrmerge package and guestfish package.
2. Run libguestfs-test-tool

Actual results:
