This is a test program, this will probably be integrated into su daemon. This hides su by bind-mounting something (/system) over /sbin, so that there is no /sbin/su binary. Usage: hidesu /proc/<one pid of the namespace>/ns/mnt This uses the fact that when a program wants access to /sdcard, zygote does this using mount namespaces, so every program accessing /sdcard will be in a custom mount namespace, that can be modified.
