# This is an attempt to replace /etc/inittab with a single shell file,
|
|
# in order to to make everything explicit and sane.
|
|
#
|
|
# The rationale is that it will make it easier to port our setup to any image
|
|
# if our minimal init is contained in a single portable file.
|
|
#
|
|
# Of course, packages that rely on extra init may start failing at any
|
|
# point with this minimized setup, but this is a risk worth taking, especially
|
|
# because gem5 is slow and basically mandates a minimal init.
|
|
#
|
|
# Here we try to some basic common init tasks that will cover what the large
|
|
# majority of software will need.
|
|
#
|
|
# We don't care about shutdown commands since we focus on stateless disks.
