Likely, it's exactly because it wants a terminal - UML puts the terminal in raw mode. Probably, instead, the script pipes the output to something, and you can't set a pipe in raw mode! However, even when I did this, I never got such an error. Thus mine is just a guess from similar situations. That said, workarounds can be: *) pass con0=xterm - con0 output (and login prompt, if you have one) will go on an xterm. *) change the script - perhaps running UML into screen, or something strange. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
