I noticed that behaviour with my CentOS6 (installed and kept up-to-date
using yum). This happened since kernel kernel-2.6.32-220.el6.x86_64 and
furthers updates. Was working as expected (my laptop's hdd mounted as
sda) with previous kernels, up to kernel-2.6.32-131.21.1.el6.x86_64.

I wonder if that behaviour, and the *change* of behaviour is an issue
that should be reported, and how to handle it on installed systems!
For now, I'm either booting w/ no USB disk plugged, or booting
a 2.6.32-131 kernel.
