Neil Williams 680a0c6fca Add option to specify the apt default release directly. 
* Add option to specify the apt default release directly and
  change the manpage content to advise on how this further
  complicates the permutations of apt configuration. Add
  commands to direct apt at the apt.conf.d and preferences.d
  directories within the chroot. (Closes: #717886)

Options:

%s replaces debootstrap to provide support for multiple
repositories, using a configuration file to specify the relevant suites,
architecture, extra packages and the mirror to use for each repository.
Example configuration:
[General]
arch=armel
directory=/opt/multistrap/
# same as --tidy-up option if set to true
cleanup=true
# same as --no-auth option if set to true
# keyring packages listed in each bootstrap will
# still be installed.
noauth=false
# extract all downloaded archives (default is true)
unpack=true
# enable MultiArch for the specified architectures
# default is empty
multiarch=
# aptsources is a list of sections to be used for downloading packages
# and lists and placed in the /etc/apt/sources.list.d/multistrap.sources.list
# of the target. Order is not important
aptsources=Debian
# the order of sections is not important.
# the bootstrap option determines which repository
# is used to calculate the list of Priority: required packages.
bootstrap=Debian
[Debian]
packages=
source=http://cdn.debian.net/debian
keyring=debian-archive-keyring
suite=stable
This will result in a completely normal bootstrap of Debian stable from
the specified mirror, for armel in /opt/multistrap/.
'Architecture' and 'directory' can be overridden on the command line.
Specify a package to extend the bootstap to include that package and
all dependencies. Dependencies will be calculated by apt so as to use
only the most recent suitable version from all configured repositories.
General settings:
'directory' specifies the top level directory where the bootstrap
will be created - it is not packed into a .tgz once complete.
