If I will install TinyCore to an usb just like the tutorial in the wiki would that make my system automaticly persistent? Or do I still need to edit the lines to make /tce /opt and /home perisistent.
The easiest way to install on a usb drive is to use USB Install in the Control Panel.
This will automatically create a /tce directory, and all applications you install will be persistent.
There are two ways you can make personal files and settings persistent.
One method is to use backup.
The other method is to use persistent /home and /opt. If you use persistent /home and /opt you need to edit lines.
If you use backup, anything you save is saved to ram. It is only saved on the usb drive when you do a backup - normally when you turn the computer off. This minimizes the amount of writing to the usb drive, so the usb drive will last longer. It also takes longer to shut down and start up the computer.
If you use persistent /home and /opt, anything you save will be written to the usb drive immediately. The usb drive will not last as long. Shutting down and starting up the computer will be faster.
