The chrooted dpkg-buildpackage process started by pbuilder inherits the TTY device you run pbuilder from as its stdout and stderr. That TTY is owned by either root or by your actual login user, depending on how you started up the root shell. So user 1234, which is the user dpkg-buildpackage is running as, doesn't have access to open that TTY device. I haven't looked at epix-lib.sh in detail, but e.g. echo Danger Will Robinson 1>&2 should work whereas echo Danger Will Robinson >/dev/stderr wouldn't. -- Daniel Schepler -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
