The Nintendo Switch homebrew and hacking scene is thriving at the moment and heres a news story about Linux running on the Nintendo Switch:
he Switch scene has been on fire since the 34c3 talk, with Team-Xecuter soon afterwards demo'ing a coldboot logo change exploit, and then later on Team Fail0verflow showing off their 'coldboot scroller' and now they are teasing yet again with Linux boot-up!
Fail0verflow have stated a month ago that they have a bootrom exploit on the Nintendo Switch, which virtually gives them full control of the console. It’s likely they’ve spent the past few weeks or months porting Linux to the console. The hacking team are very familiar with the process of porting the popular OS to consoles: most flavors of Linux running on hacked PS4s are based on their patches.
If history repeats itself though, it is possible that Fail0verflow will release their Linux patches, but not the underlying exploits. In the case of the PS4, the scene had to wait for more than a year between the time Fail0verflow released their Linux port, and the time they revealed the exploits they used to get access to the system.
