%s extends 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 debootstrap will
|
|
# still be installed.
|
|
noauth=false
|
|
# extract all downloaded archives (default is true)
|
|
unpack=true
|
|
# 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=Grip Updates
|
|
# the order of sections is not important.
|
|
# the debootstrap option determines which repository
|
|
# is used to calculate the list of Priority: required packages.
|
|
debootstrap=Debian
|
|
|
|
[Debian]
|
|
packages=
|
|
source=http://ftp.uk.debian.org/debian
|
|
keyring=debian-archive-keyring
|
|
suite=lenny
|
|
|
|
This will result in a completely normal debootstrap of Debian lenny 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 debootstap 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 debootstrap
|
|
will be created - it is not packed into a .tgz once complete.
