→Linux-based upgrading
* System running Linux can be updated from user space using '''standard applications and tools'''. Most of the times the upgrade procedures can be created using common shell commands and scripts.
* Usually, when the system provides a '''GUI''', the upgrade function is integrated in the application interface and can be activated and controlled by the user '''through graphical elements'''.
* If the '''network is available''', it's a good point that the embedded system is able to run programs like a tftp client, a ftp server/client, a ssh client (with scp program) or the wget program: with these tools, the system can easily retrieve the upgrade packages from the network.
