OS Buckaroo is defined by its relation to the game "Flight Deck Buckaroo" from the hit BBC comedy series Cabin Pressure
The goal of the game is to see which player can delete more files on their system without rendering it unbootable.
For best results: use identical systems (in VMs if you want to be safe, or on bare metal for the ultimate OS Buckaroo experience).
Note: directories are double points
10pts: file from /boot or /sys
5pts: file from /bin (or /sbin)
4pts: file from /var or /proc
3pts: file from /lib or /etc
2pts: file from /run
1pt: file from /srv or /opt
0pts: file from /mnt, /media, /home, /usr, or /tmp
