<p><b>New page</b></p><div>Its commonly reported that when users chroot into an existing linux environment on their harddrive, they encounter the <code>/dev/null: Permission Denied</code> error message. This page attempts to explain it and how to avoid it.<br />
<br />
The error is caused by mounting a filesystem with the "nodev" mount option and then chrooting into it. Knoppix automatically places a "users" mount option into the <code>/etc/fstab</code> file, which implies this "nodev" option.<br />
<br />
You can override this option by editting /etc/fstab and appending ",dev" to the options column or simply mount your new chroot filesystem by bypassing the /etc/fstab entirely by typing the following command:<br />
# mount /dev/hda1 /mnt/hda1 -o rw</div>Sandbagger
