Filesystem:/private/preboot/$boot-manifest-hash$/procursus

This is the root directory to which packages are installed to on a jailbroken rootless device using the Procursus distribution. Due to the uppercase boot manifest hash string in the path, it is symbolically linked to from /var/jb. This path was chosen because of its ability to execute binaries, not permitted in /var due to sandbox rules, and because the jailbreak can evade detection by temporarily deleting the /var/jb symbolic link.

The filesystem hierarchy below this directory is intended to be the same as the actual filesystem root.
