| 13 | <para os="a"> There are two different ways you can proceed from this point | 
|---|
| 14 | to build the final system. You can build a kernel, a bootloader, and | 
|---|
| 15 | a few other utilities, boot into the temporary system, and build the | 
|---|
| 16 | rest there. Alternatively, you can chroot into the temporary system.</para> | 
|---|
| 17 |  | 
|---|
| 18 | <para os="b">The boot method is for when you are building on a different | 
|---|
| 19 | architecture. For example, if you are building a PowerPC system from | 
|---|
| 20 | an x86, you can't chroot. The chroot method is for when you are | 
|---|
| 21 | building on the same architecture. If you are building on, and for, | 
|---|
| 22 | an x86 system, you can simply chroot. The rule of thumb here is if | 
|---|
| 23 | the architectures match and you are running the same series kernel | 
|---|
| 24 | you can just chroot. If you aren't running the same series kernel, or are | 
|---|
| 25 | wanting to run a different ABI, you will need to use the boot option.</para> | 
|---|
| 26 |  | 
|---|
| 27 | <para os="c">If you are in any doubt about this, you can try the following | 
|---|
| 28 | commands to see if you can chroot:</para> |

| 33 | <para>If either of these commands fail, you will have to follow the boot | 
|---|
| 34 | method.</para> |
