    /dev/null permission errors

    Whenever I chroot into my remaster, I get the following:

    /bin/bash: /dev/null: Permission denied
    /bin/bash: /dev/null: Permission denied
    /bin/bash: /dev/null: Permission denied
    /bin/bash: /dev/null: Permission denied
    and so on.
    I've tried doing a chmod 777 /dev/null, I've tried doing chgrp and chown root /dev/null, and I still get the same error. I searched Google for solutions, but their problems were all fixed after a chmod 777, whereas mine still persists.
    I can delete /dev/null and it regenerates one and works, but then the remaster fails to work when installed onto the HD, and the regenerated /dev/null is quite odd - it's not even a device file. Any thoughts?

    RE

    U must mount the drive that u want to chroot with

    mount -rw /dev/hda1 /mnt/hda1

    changing hda1 with your specific devices
    good luck

    The drive's already mounted rw, and before you ask, I'm root.

    Well, I understood it (almost ), but where does it talk about /dev/null? It gives a guide to installation of Mandrake and use of Morphix, doesn't it?

    One of the remastering procedures I read says about /dev/null permission errors to do this:

    mount -o remount,rw,nosuid -t ext2 /dev/hdaN /mnt/hdaN

    remount -o dev

    in knoppix, if you mount /mnt/hdx, it is by default mouted with the nodev option, so /dev/null won't work there. Before chrooting, you should do mount -oremount,dev /mnt/hdxy
