-====== chroot - Mounting /dev in a chroot environment ======
-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:
-<code bash>
-mount fstype -t fstype /tmp/chroot/mountpoint
-</code>
-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:
-<code bash>
-mount --bind /dev /tmp/chroot/dev
-</code>
-Or to make it shorter:
-<code bash>
-mount -B /dev /tmp/chroot/dev
-</code>
-Now, **/tmp/chroot/dev** will be populated with the same content than the host's **/dev** which will allow you to do a grub-update and much more within the chroot.
