Magsik 19.4 brings Android 10 support and new system as root implementation
Recognized developer topjohnwu helped giving an alternative to many devices for an supersu alternative and the ability to install lots of modules and tweaks in its own Magisk manager.
The developer started with Magisk as a systemless root method and has grown and improving in these many years into a much useful and productive tool rather than just plain root. But even if you are finding an alternative for supersu Magisk is a recommended rooting method for many devices out there
The latest update to Magisk comes in the form of Magisk 19.4 release that brings over Android 10 support, support for product partition, and a new system-as-root implementation.
Android supports two types of partition layout: the traditional partitioning scheme (where the ramdisk is present in the /boot partition and mounted as rootfs and system is mounted at /system), and the newer A/B partitioning scheme, where the system is mounted as rootfs. Google has made system-as-root mandatory for devices launching with Android 9 Pie (because of changes done for Project Treble), while A/B partitioning continues to remain a recommended but optional feature due to the changes it requires. In Android 10, the root file system is no longer included in the ramdisk and is now instead merged within system.
Magisk has supported system-as-root devices ever since the first Google Pixel, but the implementation used had scope for a few issues. With Magisk v19.4, Magisk will actually mount system to / (root) as part of the new system-as-root implementation. Now you wont find the /system as a longer a valid mount point, the root directory is no longer rootfs, but system, and the overlay system is also different. This update and the changes allow Magisk to support Android 10 on A/B devices with fully functioning MagiskHide. Module developers can also now properly modify files present in the product partition. Support for A-only devices running Android 10 will come in a future update.
