Part 3: Rootful vs. Rootless – What Is the Difference?

When jailbreaking the iPhone 7 on iOS 15.7.3 with palera1n, you will face a choice: Rootful or Rootless.

Rootful (traditional): The jailbreak modifies the root filesystem (/), allowing old tweaks (pre-iOS 15) to work. Palera1n achieves this via a fakefs (fake filesystem). This is more unstable and consumes storage space but has the widest tweak compatibility.
Rootless (modern): The jailbreak keeps the root filesystem read-only (as Apple intended) and installs tweaks to /var/jb (or similar). This is more stable, safer, and the recommended method for iOS 15.7.3. However, many older tweaks need to be updated for rootless.

Recommendation for iPhone 7 users: Use palera1n rootless mode unless you have a specific legacy tweak that requires rootful. Performance on the A10 chip is better with rootless.
