Package: debootstrap Version: 1.0.42 Severity: wishlist Tags: patch Dear Maintainer, I wonder if we could have debootstrap support the repository ftp.debian-ports.org. Please find the script attached as an illustration of the requested features, in the form of a script /usr/share/debootstrap/scripts/debian-ports. (A diff against the stock script for unstable is attached as from_unstable_to_debian-ports.diff.gz) ftp.debian-ports.org hosts unofficial architectures until they are integrated in the main Debian archive (currently alpha, hppa, m68k, powerpcspe, ppc64, sh4 and sparc64, and GNU/Hurd). It requires specific workarounds in debootstrap since the needed packages are sometimes not in the "unstable" suite of the repository. Thanks in advance !

Description: Binary data
debootstrap and debian-ports ---------------------------- Usage ----- debootstrap debian-ports target-directory or debootstrap [ some options ] debian-ports target-directory [ a_debian-ports_mirror] Make sure that the script is installed as /usr/share/debootstrap/scripts/debian-ports. (If not, give the actual location of the script as the last argument of debootstrap, e.g. debootstrap unstable my_target_directory http://ftp.de.debian.org/debian-ports ./debian-ports using the mirror ftp.de.debian.org with a copy of the script in the current working directory.) Why a debootstrap script ? -------------------------- According to the description on http://www.debian-ports.org and http://www.debian-ports.org/archive : "The goal of this machine is to provide an infrastructure for unofficial architectures until they are integrated in the main Debian archive. " "The archive is currently shared between GNU/Linux alpha, hppa, m68k, powerpcspe, ppc64, sh4 and sparc64, and GNU/Hurd." There are 3 suites : unstable, unreleased and experimental. "The unreleased suite : this suite is used to upload packages which need hacks to build until the changes are integrated into Debian." It occurs that the needed files for an initial installation with debootstrap are spread among both suites unstable and unreleased. And the main code of debootstrap allows for one sole suite. Please note that no support for experimental packages is provided here. Under the hood -------------- The script symlinks unreleased as a (fake) component "mainunreleased" of unstable. The default mirror is changed to ftp.debian-ports.org and the default keyring to debian-ports-archive-keyring. debian-ports-archive-keyring (Prority : extra) is selected for installation in the target. A line for unreleased is added to sources.list.
