# Configuration for the shell process job.
#
# Executes a list of commands found under the key *script*.
# If the top-level key *dontChroot* is true, then the commands
# are executed in the context of the live system, otherwise
# in the context of the target system. In all of the commands,
# the following substitutions will take place:
#  - `@@ROOT@@` is replaced by the root mount point of the **target**
#    system from the point of view of the command (for chrooted
#    commands, that will be */*).
#  - `@@USER@@` is replaced by the username, set on the user page.
#
# The (global) timeout for the command list can be set with
# the *timeout* key. The value is a time in seconds, default
# is 10 seconds if not set.
#
# If a command starts with "-" (a single minus sign), then the
# return value of the command following the - is ignored; otherwise,
# a failing command will abort the installation. This is much like
# make's use of - in a command.
#
# The value of *script* may be:
#   - a single string; this is one command that is executed.
#   - a single object (this is not useful).
#   - a list of items; these are executed one at a time, by
#     separate shells (/bin/sh -c is invoked for each command).
#     Each list item may be:
#     - a single string; this is one command that is executed.
#     - a single object, specifying a key *command* and (optionally)
#       a key *timeout* to set the timeout for this specific
#       command differently from the global setting.
#
# Using a single object is not useful because the same effect can
# be obtained with a single string and a global timeout, but when
# there are multiple commands to execute, one of them might have
# a different timeout than the others.

# Script may be a single string (because false returns an error exit

# script: "/usr/bin/false"

# Script may be a list of strings (because false returns an error exit
# code, **but** the command starts with a "-", the error exit is
# ignored and installation continues):

#     - "-/usr/bin/false"
#     - "/bin/ls"
#     - "/usr/bin/true"

# Script may be a lit of items (if the touch command fails, it is
# ignored; the slowloris command has a different timeout from the
# other commands in the list):
