When working in a chrooted environment, there is a few special file systems that needs to be mounted so all programs behave properly.
For instance, grub will need to access your disk devices….
While most special file systems might be mounted with:
# mount fstype -t fstype /tmp/chroot/mountpoint
Where fstype will be sysfs, proc, /dev is not following this rule.
In order to mirror /dev, you will need to actually bind /tmp/chroot/dev to your host system’s /dev .
This can be done through the following command:
# mount –bind /dev /tmp/chroot/dev
Or to make it shorter:
# mount -B /dev /tmp/chroot/dev
