Have you ever needed a USB pen drive with a fully functional Linux installation that you can take with you?
This is called a persistent USB and differs from the usual live USB where you try out the distribution before installing but you cannot safe your work or desktop configuration on that same pen drive. This means that you will loose your work whenever you shutdown a live session. A persistent USB functions like a regular installation on a hard drive but with the added bonus that you can easily take it with you wherever you go.
Depending on the pen drive and your system’s USB version the installation can take a while. It took me almost two hours to finish. So, just let your computer do its job and do something useful in the meantime 😉
