Andrzej is using a glibc that "does not support minors > 255".
The oldest glibc I have around here is glibc-2.2.5-34 and it passes Andrzej's `for a in $(seq 4);do ssh -t remote tty;done' test OK. I do not know at which version they started to permit larger values for minors, but it must have been some time ago.
A small number of people are hurting from the removal of first-fit pty allocation and I do think it needs to be put back. I have a patch but neither Peter nor I have actually tested it yet. I'll aim to get it into 2.6.6. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
