			<pre>
			$ ls -l /dev/disk/by-uuid

			Once you've got it, edit <code>/mnt/linux/etc/fstab</code> and add a line:

Created page with "Sheesh. First, I partition my / directory too small on my desktop box, and have to move the /usr directory to a new partition. Then, I partition my / directory too small on..."

New page

Sheesh.

First, I partition my / directory too small on my desktop box, and have to move the /usr directory to a new partition.

Then, I partition my / directory too small on my laptop, and have to move the /root directory to a new partition.

Okay, let's roll up our sleeves and fix this crap.

=Boot into Live USB=

First step is to boot into a live CD.

Use Kali or Pentoo as your live distro. Why the hell would you use anything else.

=Map Out Partitions=

==Gparted==

Fire up parted or gparted or fdisk or whatever your "favorite" disk manager is. Get a snapshot of what's where.

The partition we mount as / is on /dev/sda5 and the partition we want to mount as /root is on /dev/sda6. Assume /dev/sda6 is empty (not necessary though).

=Copy, Don't Move=

We'll start by copying files, not moving them, in case something goes awry.

==Mount The Partitions==

Mount the / partition:

<pre>
$ mkdir /mnt/linux
$ mount /dev/sda5 /mnt/linux
</pre>

Mount the /root partition:

<pre>
$ mkdir /mnt/myhome
$ mount /dev/sda6 /mnt/myhome
</pre>

==Copy the Files==

Now we copy (don't move) things from <code>/mnt/linux/root</code> to <code>/mnt/myhome/root</code>:

<pre>
$ cp -r /mnt/linux/root /mnt/myhome/root
</pre>

==Edit Fstab==

The last step is to

=Test=

==Move, Don't Delete==

Now that we've finished the copy, and the files are successfully duplicated, we can move (don't delete!) the original:

<pre>
$ mv /mnt/linux/{,_}root
</pre>

==Reboot==

Now we test things out by rebooting. Make sure /root mounts as expected.

=Finishing=

We finish by making our changes permanent. We can boot into a live distro again, or just do it from our installed distro.

Remove the old files from the current installed distro:

<pre>
$ rm -r /_root
</pre>

Remove the old files from a live distro:

<pre>
$ mkdir /mnt/linux
$ mount /dev/sda5 /mnt/linux
$ rm -r /mnt/linux/_root
</pre>
