Currently, if your process requires linux capabilities then you cannot use
this command. You must instead request the capabilities in-process while
still root, and then drop to your desired uid.
As of Android M, processes should use this option even if they
require linux capabilities. Previously, to acquire linux
capabilities, a process would need to run as root, request the
capabilities, then drop to its desired uid. There is a new
mechanism through fs_config that allows device manufacturers to add
linux capabilities to specific binaries on a file system that should
be used instead. This mechanism is described on
