Root Implementations

Kernel-based su and root access management for Android.

Root Flavor	Description	Source
KernelSU	Original implementation by tiann — the foundation from which all other variants are derived.	tiann/KernelSU
KernelSU-Next	Created by rifsxd. SUSFS-integrated builds sourced from pershoot.	KernelSU-Next/KernelSU-Next · pershoot/KernelSU-Next
ReSukiSU	Fork of SukiSU, also has its own SUSFS-integrated branch.	ReSukiSU/ReSukiSU

Root Hiding

Feature	Description	Source
susfs4ksu	Root-hiding add-on for KernelSU using kernel patches and a userspace module. Recommended module: sidex15/susfs4ksu-module.	simonpunk/susfs4ksu
Ptrace Leak Fix	Fixes ptrace info leak on kernels older than 5.16. Internal to root hiding.	patch
Unicode Fix	Prevents path traversal via non-printable Unicode (experimental). Internal to root hiding.	patch 6.1- · patch 6.1+

Meta Module

Module	Description	Source
NoMount	Metamodule providing mount-related functionality alongside root implementations.	maxsteeel/nomount
Mountify	Globally mounted modules via OverlayFS.	backslashxx/mountify

Note

Only one is required if mounting modules.

Which one should I use?

• NoMount — recommended, bundled as nomount-metamodule in CI.
• Mountify — alternative OverlayFS approach, not bundled — install latest compatible module manually.
