The kR105 name could tell you something because this developer was recently credited by CTurt for his work PS4 hack. KR105 has just released a fully operational exploit.
He managed to integrate Linux support and even gave himself the luxury of providing some tools directly usable on Linux PS4.
In other words, kR105 just released everything you need to run Linux on PS4. Be careful, your PS4 must have a 1.76 firmware. All this was confirmed by CTurt.
About a week ago was released the exploit dlclose, but incomplete, kR105 corrected the feat so that it could run Linux natively on 1.76 (simplifying).
The launch of Linux has simplified, it was necessary to launch a loader Linux and then launched its own compilation, henceforth the implementation is simpler. It is necessary to use PS4-Playground (of CTurt) to then launch its compilation from a USB key formatted in FAT32.
A Compiled distro of Linux for the PS4. KR105 has the files bzImage and initramfs.cpio.gz ready for anyone to grab, so you do not have to compile your own version. In his words: "those files should get you into linux with a nice bash console on your tv".

Update: As pointed out by CTurt, you can simply http://wololo.net/downloads/index.php/download/8385 put them on a FAT32 USB stick that you’ll connect to your 1.76 PS4, and test directly by http://cturt.github.io/PS4-playground/
Wow, now that’s a good start for the weekend!
