A KSU-less telephone system is a type of electronic key telephone system that puts the switching circuitry inside of each individual phone. [1] .

Manual VFS Hooks are now supported for both NON-GKI/GKI kernels, if you decide to use manual hooks for both NON-GKI/GKI then make sure to do CONFIG_KSU_WITH_KPOBES=n (it's not really necessary to disable CONFIG_KPROBES now) & if you want to use KPROBES Hooks then make sure to do both CONFIG_KPROBES=y and CONFIG_KSU_WITH_KPROBES=y (KPROBES is ...

It uses a central switching device – the key system unit – to manually determine the phone-line selection. The variation of this system is called KSU-Less, which has the same phone capabilities as the basic system; however, it is portable and flexible, as it does not use the central switching unit, and it’s entirely wireless.

Required module to use applications such as AdAway on KernelSU and APatch - symbuzzer/systemless-hosts-KernelSU-module

获取官方固件的方法有很多，如果你的设备支持 fastboot boot，那么我们最推荐以及最简单的方法是使用 fastboot boot 临时启动 KernelSU 提供的 GKI 内核，然后安装管理器，最后在管理器中直接安装；这种方法不需要你手动下载官方固件，也不需要你手动提取 boot。 如果你的设备不支持 fastboot boot，那么你可能需要手动去下载官方固件包，然后从中提取 boot。 与 GKI 模式不同，LKM 模式会修改 ramdisk，因此在出厂 Android 13 的设备上，它需要修补的是 init_boot 分区 …

A KSU-less system has comparable features to a smaller commercial telephone system. The key difference is that the communication technology is directly located inside the telephones.

This module installs a userspace helper tool called ksu_susfs and sus_su into /data/adb/ksu and provides a script to communicate with SUSFS kernel. This module provides root hiding for …

KernelSU 提供了一个模块机制，它可以在保持系统分区完整性的同时达到修改系统分区的效果；这种机制通常被称之为 systemless。 KernelSU 的模块运作机制与 Magisk 几乎是一样的，如果你熟悉 Magisk 模块的开发，那么开发 KernelSU 的模块大同小异，你可以跳过下面有关模块的介绍，只需要了解 KernelSU 模块与 Magisk 模块的异同。 KernelSU 的模块支持显示界面并与用户交互，请参阅 WebUI 文档。 KernelSU 提供了一个功能完备的 BusyBox 二进制文件（包括完整 …

KSU-less systems - A growing number of phone systems have all of the circuitry that used to be housed inside a KSU built into the phones. They are called "KSU-less" systems. You can get a system with all corded phones, or a mix of corded and cordless.

There are three main considerations with a KSU-less phone system: An increasingly larger number of KSU-less systems are actually cordless phone systems. Of course, these phones will need to be charged with a power cord, but they can be placed just about anywhere. They also can have cords that plug into standard telephone jacks.
