From: Stefano Babic <sbabic@nabladev.com>

Detecting the init manager from /sbin/init does not always work and it
fails when etc-overlayfs is used, because first the
pre-init script is called and init is renamed as init.orig.. Read the
process name with pid = 1 from /proc, and use it to detect the init manager.
