When using openvt, it always fails with a 'duplicated stdin' error. Printed on what would be the new VT is: 'duplicated stdout' 'duplicted stderr' I've tried this on 7.0 i386 and Alpha and it fails the same way on both.
Can't reproduce this (console-tools-19990829-29).
Just pulled console-tools-19990829-30 out of rawhide, still fails the same way.
Doesn't happen here. Please attach the output of strace openvt.

FWIW, I copied over the openvt binary from a Debian-Potato system (this was on Alpha) and their binary works fine on 7.0.
