55 is run in its own session (setsid(2)) and possibly with a
56 controlling tty (TIOCSCTTY). This is not the traditional init
57 behavour, but is often what you want in an embedded system where
58 the console is only accessed during development or for maintenance.

90 Legacy support for running init under the old-style initrd. Allows
91 the name linuxrc to act as init, and it doesn't assume init is PID 1.

93 This does not apply to initramfs, which runs /init as PID 1 and
94 requires no special support.
