Some tools (e.g. su, parts of the PAM stack) try to perform audit
operations (e.g. write to the log) in the container and refuse to work
if the operations fail. This is really a bug in those tools, but
too prevalent to fix atm.

-b mean to boot init in the container, and 3 becomes an arg for the
init binary. Should mean runlevel 3 (or runlevel3.target) in this
case.
