====== UUID or Universally Unique Identifier ======

If you install Tinycore manually, you may include something like tce=sda1.

If install Tinycore using the installer, it includes something like tce=UUID="9aff3da3-474d-440d-bb6c-3240afe84ac6"

This UUID is a Universally Unique Identifier.

==== Fixed Drives and Removable Drives ====

If you install to a fixed drive, such as a hard drive in a computer, it's location will not change, so you can use tce=sda1 (you can use either tce=sda1 or tce=UUID).

If you install to a removable drive, such as a USB drive, it may be sda1, sdb1, sdc1, sdd1 or sde1, depending on which computer or USB slot you are using.

If you were to include tce=sda1, you may not be able to load applications if used in a computer or USB slot which identifies the drive as sdb1, sdc1, sdd1 or sde1.

If the UUID is used, it will always be the same, and work in other computers.

==== Persistent home and opt on Removable Drives ====

If you have installed Tinycore using the installer, and already have tce=UUID="9aff3da3-474d-440d-bb6c-3240afe84ac6" and want to include persistent home and opt on a removable drive, copy the UUID. Like this

<code>opt=UUID="9aff3da3-474d-440d-bb6c-3240afe84ac6" tce=UUID="9aff3da3-474d-440d-bb6c-3240afe84ac6" home=UUID="9aff3da3-474d-440d-bb6c-3240afe84ac6"</code>

==== Find Out UUID ====

If you have not installed Tinycore using the installer, and want to find out the UUID, use

<code>blkid -s UUID /dev/sda1</code>

If not sda1, use the correct partition.
