Development Notes

Organization of the VM

By default the following organization is used, but the config/environment.sh file allows for some of these paths and names to be changed:

The ubuntu user has sudo access.
ctf-* scripts are added to /usr/local/bin
The ctf user is given sudo permissions to run the ctf-* scripts, but otherwise has no sudo access.
Levels are stored under /var/ctf/levels
Passwords are stored in /var/ctf/passwords.txt and in per-level files.
Levels are marked unlocked with a file /var/ctf/levels/<level>.unlocked.

If developing on the VM without exporting it you will want to run rm /EMPTY before starting to ensure that it doesn't fill up.
