This will result in a completely normal debootstrap of Debian lenny from

|
|
|
the specified mirror, for ARM in /opt/multistrap/.
|
|
|
|
|
|
|
|
'Architecture' and 'directory' can be overridden on the command line.
|
2009-03-05 19:07:21 +00:00
|
|
|
|
|
|
|
Specify a package to extend the debootstap to include that package and
|
|
|
|
all dependencies.
|
|
|
|
|
|
|
|
Specify a script only if the suite is not currently supported by
|
|
|
|
debootstrap (which in turn are based on Debian and Ubuntu suite names).
|
|
|
|
|
|
|
|
Useful options can include --no-resolve-deps if one of the repositories
|
|
|
|
contains packages that are also in any of the other repositories but at
|
|
|
|
a lower version. This prevents debootstrap unpacking the older version
|
|
|
|
of the duplicated package.
|
|
|
|
|
|
|
|
General settings:
|
|
|
|
|
|
|
|
The order of repositories specified in the debootstrap (under General),
|
|
|
|
determines which repository is unpacked first - this is important if one
|
|
|
|
repository is incomplete or contains older versions.
|
|
|
|
|
|
|
|
'directory' specifies the top level directory where the debootstrap
|
|
|
|
will be created - it is not packed into a .tgz once complete.
|
|
|
|
|
|
|
|
'retries' determines how many times debootstrap should be allowed to
|
|
|
|
restart (the same value is used for all repositories) to allow for
|
|
|
|
temporary network issues.
|
|
|
|
|
|
|
|
If 'arch' does not match the build architecture (determined using
|
|
|
|
`dpkg-architecture -qDEB_BUILD_ARCH`, --foreign is passed to
|
|
|
|
each debootstrap.

determines which repository is unpacked first - this is important if one
|
|
|
|
repository is incomplete or contains older versions.
|
|
|
|
|
|
|
|
'directory' specifies the top level directory where the debootstrap
|
|
|
|
will be created - it is not packed into a .tgz once complete.
|
|
|
|
|
|
|
|
'retries' determines how many times debootstrap should be allowed to
|
|
|
|
restart (the same value is used for all repositories) to allow for
|
|
|
|
temporary network issues.
|
|
|
|
|
|
|
|
If 'arch' does not match the build architecture (determined using
|
|
|
|
`dpkg-architecture -qDEB_BUILD_ARCH`, --foreign is passed to
|
|
|
|
each debootstrap.

|
Note that em_multistrap deliberately turns off Install-Recommends.
|
|
|
|
|
|
|
|
As with debootstrap, em_multistrap will continue after errors although
|
|
|
|
you may want to purge $directory/var/cache/apt/archives from time to
|
|
|
|
time.

|
em_multistrap does not currently implement machine:variant support
|
|
|
|
but the build directory is not packed up at the end of the run so
|
|
|
|
other scripts can be used to implement customisations.
