Bananymous b523ccb893 AOC2023: Implement day8 
Second part was kinda weird. You are supposted to assume something
of the input, which necessarily is not true.

Bananymous 3ed25425a3 AOC2023: implement day3 
Solution to second puzzle is not optimal, it definately should be
O(1) space, but I didn't want to think about it.

Bananymous 7090388c70 cp: allow copying all files except directories 
The old condition seemed odd. This allows taking screen shots by
copying the /dev/fb0.

Bananymous ff550785a7 Userspace: Implement basic image rendering for Netbpm 
You can now render Netbpm (P6) format image to framebuffer using
`image` command. I added basic test image to
/usr/share/images/sample.ppm

Bananymous 056586486d Shell: make clear use \e[2J instead of \e[J 
This makes kernel to actually clear the full screen. If framebuffer
did not fit font exactly last row would be left partially uncleared

Bananymous f6c312a6b3 BuildSystem: using sysroot doesn't need root privileges anymore! 
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.

Bananymous 07f8c972b3 Shell: Set get old termios earlier 
I sourced the config file before getting old termios. Sourcing
updated the termios so old_termios was always in non canonical, non
echoing mode.
