What is resukisu?

ReSukiSU is a tool that gives Android users "root" access to their phones, meaning full control over the device's operating system. It's a customized version of an existing root solution called SukiSU-Ultra, with extra tweaks aimed at making the software more stable and easier to build from source. Root access lets you modify your phone's system at the deepest level, which is useful for things like uninstalling pre-installed carrier apps, running specialized backup tools, or applying custom visual themes. The project works by integrating directly into the phone's kernel, the core layer of the operating system. It includes a module system that lets you plug in these modifications without permanently altering your system files, making changes easier to undo. It also features an "App Profile" system that acts like a cage, restricting how much root power individual apps can access so a rogue app can't take over your device. This tool is designed for Android power users and enthusiasts who want fine-grained control over their devices. For example, someone with an older phone running a kernel version as far back as 3.4 can use it, though they will need to build the kernel manually. It also supports newer GKI 2.0 devices running kernel 5.10 and above. The project notes broad compatibility, supporting several different processor architectures and working alongside other root managers like Official KernelSU, RKSU, MKSU, and SukiSU. A notable aspect of the project is its inclusion of KPM (KernelPatch Module) support, which is still a work in progress to ensure compatibility across different root implementations. It also includes SuSFS, a tool designed to hide the fact that the phone is rooted, which some users need for certain banking or security apps to function properly. The README doesn't go into detail on exactly how every feature behaves in daily use, but it clear the project is built by pulling together the best parts of several other open-source root projects.
