+/* magiskinit.c - Workaround for skip_initramfs devices
+ *
+ * This code has to be compiled statically to work properly.
+ *
+ * Magiskinit will mount sysfs, parse through uevent files to make the system block device,
+ * then it'll mount the system partition and clone rootfs except files under /system.
+ * Folders placed in "overlay" will then be overlayed to the root.
+ * Lastly before giving control back to the real init, it'll patch the root files to load Magisk.
