✍️ Author Comment

Some limitations and bad practice that are concerning and hopefully avoided in the future:

• Procedural DFS implementation in Filesystem
• EXT2 Filesystem requires a big amount of stack memory (4KB at least)
• User Shell own strtoken implementation, sometimes fail reading command name even though it's correct
• Badapple implementation using 1.4MB stack size, OS may prone to crash if not implemented properly
