Encyclopedic overview
iOS jailbreaking is the use of a kernel exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based operating systems.
While legacy jailbreaks modified the system partition, modern 'rootless' jailbreaks (iOS 15+) work around the Sealed System Volume (SSV) to grant root access (UID 0) and sandbox escapes without modifying the read-only root filesystem. This allows for the installation of software and tweaks unavailable through the App Store by localizing them within a writable directory named /private/preboot/$boot-manifest-hash$/procursus, accessed through the /var/jb symlink for quick accessibility.
