=== Status ===
=== Status ===
* Debian chroot construction has been automated: see [http://dev.laptop.org/git/users/mstone/puritan/snapshot/puritan-sugar.tar.bz2 puritan-sugar.tar.bz2] and its [http://dev.laptop.org/git/users/mstone/puritan/tree/README?h=sugar README] -- [[User:Mstone|Michael Stone]] 20:33, 1 August 2009 (UTC)
* sugar-chroot-0.1 released: see [http://dev.laptop.org/git/users/mstone/sugar-chroot sugar-chroot]
=== Chroot Construction ===
=== Purpose ===
You want to test sugar, sugar patches, sugar packages, or sugar hacks. You want clean, reproducible environments. You want sugar-chroot.
=== Usage ===
As excerpted from the '''[http://dev.laptop.org/git/users/mstone/sugar-chroot/plain/README README]''':
sugar-chroot consists of simple scripts. Download and unpack them like so:
==== Debian squeeze chroot ====
NV=sugar-chroot-0.1
curl http://dev.laptop.org/~mstone/releases/SOURCES/$NV.tar.xz | tar Zxf $NV.tar.xz
cd $NV
To use them, pick a supported distro:
DISTRO=debian
DISTRO=fedora
To configure:
echo $DISTRO > conf/distro
$EDITOR conf/$DISTRO.mk
Then run
sudo make r/distro
sudo debootstrap --arch i386 squeeze $CHROOT http://localhost:9999/debian
to install your chroot.
=== History ===
See http://wiki.sugarlabs.org/index.php?title=Development_Team/Chroot&oldid=36911 for the manual instructions which sugar-chroot automates.
