 ### Basic utility of what we call a "kernel"
 
-- Fix terminal driver (backspace issues, scrolling) OR add Flanterm or equivalent
 - Implement tasks, and task switching + context switching and spinlock acquire/release
 - Load an executable
 - Filesystem (TAR for read-only initfs, then maybe read-write using FAT12/16/32 or easier fs) w/ VFS layer

 - SOME error handling in functions
 - Unit tests
 - Good error codes (like Linux kernel: ENOMEM, ENOENT, ...)
-- Make the panic function work within itself without dependencies + error message (and still get cpu context?)
