| − | * 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] |
| − | * Sugar continues to run happily in Squeeze chroots. --[[User:Mstone|Michael Stone]] 16:30, 3 July 2009 (UTC)
| |
| − | * Sugar is now somewhat runnable from chroots. Jaunty and Squeeze have been tested recently; Fedora has not. --[[User:Mstone|Michael Stone]] 22:21, 23 May 2009 (UTC)

| | | | |
| − | === Chroot Construction === | + | === Purpose === |
| | | | |
| − | There are lots of ways to create appropriate chroots; e.g. by hand, with debootstrap, with mock, etc.
| + | You want to test sugar, sugar patches, sugar packages, or sugar hacks. You want clean, reproducible environments. You want sugar-chroot. |
| | | | |
| − | Here are some ideas to help you get started:
| + | === Usage === |
| | | | |
| − | ==== Ubuntu jaunty chroot ====
| + | As excerpted from the '''[http://dev.laptop.org/git/users/mstone/sugar-chroot/plain/README README]''': |
| − | With ''recent'' versions of debootstrap, in order to get a working chroot, you want something like:
| |
| | | | |
| − | export CHROOT=`pwd`/jaunty-root
| + | sugar-chroot consists of simple scripts. Download and unpack them like so: |
| − | sudo debootstrap --arch i386 jaunty $CHROOT http://ubuntu.media.mit.edu/ubuntu/
| |
| − | sudo chroot $CHROOT /bin/bash -l
| |
| − | mount -t proc proc /proc
| |
| − | mount -t devpts devpts /dev/pts
| |
| | | | |
| − | ==== Debian squeeze chroot ==== | + | NV=sugar-chroot-0.1 |
| − | With debootstrap, in order to get a working chroot, you want something like:
| + | curl http://dev.laptop.org/~mstone/releases/SOURCES/$NV.tar.xz | tar Zxf $NV.tar.xz |
| | + | cd $NV |
| | | | |
| − | export CHROOT=`pwd`/sid-root
| + | To use them, pick a supported distro: |
| − | sudo debootstrap --arch i386 squeeze $CHROOT http://debian.lcs.mit.edu/debian
| |
| | | | |
| − | # and some of the following: | + | DISTRO=debian |
| − | mount -t tmpfs tmpfs $CHROOT/tmp | + | DISTRO=fedora |
| − | mount -t proc proc $CHROOT/proc
| |
| − | mount -t devpts devpts $CHROOT/dev/pts
| |
| − | mount -t selinuxfs selinux $CHROOT/selinux
| |
| | | | |
| − | # and to enter the chroot
| + | To configure: |
| − | sudo chroot $CHROOT /bin/bash -l
| |
| | | | |
| − | ''Reference: http://www.debian.org/doc/manuals/reference/ch-tips.en.html ''
| + | echo $DISTRO > conf/distro |
| | + | $EDITOR conf/$DISTRO.mk |
| | | | |
| − | ''Note'': you can use approx to cache packages across multiple runs for faster testing:
| + | Then run |
| | | | |
| − | apt-get install approx
| + | sudo make r/distro |
| − | echo 'debian http://debian.lcs.mit.edu/debian' >> /etc/approx/approx.conf
| |
| − | /etc/init.d/approx restart
| |
| − | sudo debootstrap --arch i386 squeeze $CHROOT http://localhost:9999/debian | |
| | | | |
| − | ==== Fedora rawhide chroot ====
| + | to install your chroot. |
| | | | |
| − | We will use <tt>febootstrap</tt> to construct our Fedora chroot. Install it with:
| + | === History === |
| | | | |
| − | yum install febootstrap # or
| + | See http://wiki.sugarlabs.org/index.php?title=Development_Team/Chroot&oldid=36911 for the manual instructions which sugar-chroot automates. |
| − | apt-get install febootstrap
| |
| − | | |
| − | : ''(Note for Debian users -- Fedora 11 and up require versions of <tt>rpm</tt> built with fancy features. I have successfully run these instructions with rpm_4.7.1-4_i386, which, at the time, I built from sources in Debian Experimental.)''
| |
| − | | |
| − | Then run it like so:
| |
| − | | |
| − | export CHROOT=`pwd`/f11
| |
| − | sudo febootstrap fedora-11 $CHROOT # sugar-0.84
| |
| − | | |
| − | or
| |
| − | | |
| − | export CHROOT=`pwd`/f12
| |
| − | sudo febootstrap fedora-12 $CHROOT # sugar-0.85.5, at the time of writing
| |
| − | | |
| − | Finally, as with Debian:
| |
| − | | |
| − | # and some of the following:
| |
| − | mount -t tmpfs tmpfs $CHROOT/tmp
| |
| − | mount -t proc proc $CHROOT/proc
| |
| − | mount -t devpts devpts $CHROOT/dev/pts
| |
| − | mount -t selinuxfs selinux $CHROOT/selinux
| |
| − | | |
| − | # and to enter the chroot
| |
| − | sudo chroot $CHROOT /bin/bash -l
| |
| − | | |
| − | ==== Gentoo chroot ====
| |
| − | | |
| − | Well, if you are familiar with regular Gentoo installation process(by using [http://www.gentoo.org/doc/en/handbook/ Handbook] instead of GUI stuff) you should know how to setup Gentoo chtoot :). Otherwise use these instructions.
| |
| − | | |
| − | * Firstly, you need Gentoo stage tarball. You can borrow it from any [http://www.gentoo.org/main/en/mirrolrs2.xml mirror] (use releases/<platform>/current sub directory).
| |
| − | | |
| − | * Lets think you are using stage3-i686-20090623.tar.bz2, then:
| |
| − | | |
| − | mkdir chroot-gentoo
| |
| − | tar xjpf stage3-i686-20090623.tar.bz2 -C chroot-gentoo
| |
| − | mount -o bind /dev chroot-gentoo/dev
| |
| − | mount -o bind /proc chroot-gentoo/proc
| |
| − | chroot chroot-gentoo /bin/bash
| |
| − | | |
| − | * To install sugar, use [[Community/Distributions/Gentoo|sugar-overlay]] or setup [[Development_Team/Jhbuild|sugar-jhbuild]] environment(with [[Community/Distributions/Gentoo#Packages|sugar-overlay]] you can install git packages as well).

| − | === Sugar Installation === | |
| − | | |
| − | ==== jaunty chroot ====
| |
| − | | |
| − | sed -ie "s/main/main universe/" /etc/apt/sources.list
| |
| − | apt-get update
| |
| − |
| |
| − | apt-get install locales
| |
| − | locale-gen "$LANG"
| |
| − | dpkg-reconfigure tzdata
| |
| − |
| |
| − | apt-get install sugar sugar-activities
| |
| − |
| |
| − | # install your development tools here
| |
| − |
| |
| − | # patch (hopefully temporary) bugs
| |
| − | sed -ie '114i\\ if not favorites_settings.layout: favorites_settings.layout = favoriteslayout.RingLayout.key' /usr/lib/python2.6/dist-packages/jarabe/desktop/favoritesview.py
| |
| − | | |
| − | ==== squeeze chroot ====
| |
| − | | |
| − | apt-get update
| |
| − | apt-get install locales
| |
| − | dpkg-reconfigure locales
| |
| − |
| |
| − | # edit /etc/hosts
| |
| − | | |
| − | apt-get install education-desktop-sugar sugar-0.84
| |
| − |
| |
| − | # install your development tools here
| |
| − | | |
| − | ==== f12 chroot ====
| |
| − | | |
| − | yum groupinstall sugar-desktop
| |
| − | | |
| − | | |
| − | ==== f11 chroot ====
| |
| − | | |
| − | yum groupinstall sugar-desktop
| |
| − | | |
| − | === User Accounts ===
| |
| − | | |
| − | For stupid reasons, it's necessary that Sugar run under a uid inside the chroot which exists as a real account outside the chroot. (Talk to the DBus people.)
| |
| − | | |
| − | Consequently, ''as root'', run something like this ''both'' inside and outside the chroot:
| |
| − | | |
| − | groupadd -g 64002 sugar
| |
| − | useradd -m -u 64002 -g sugar -s /bin/bash sugar
| |
| − | | |
| − | === D-Bus ===
| |
| − | | |
| − | Sugar wants to be able to use global state stored in both HAL and NetworkManager, both of which live on the system bus. Consequently, ''outside the chroot'', we need to
| |
| − | | |
| − | sudo mount --bind /var/run/dbus $CHROOT/var/run/dbus
| |
| − | | |
| − | before entering the chroot. (Mock uses unshare() to enter a new mount-point namespace since this makes garbage collection of mountpoints much easier.)
| |
| − | | |
| − | === X11 ===
| |
| − | | |
| − | We need to point Sugar at an X server. One easy (but insecure) way to do this is to make a nested X server like so, ''outside the chroot'':
| |
| − | | |
| − | Xephyr -ac :1 -screen 800x600x24 # 1024x768x24
| |
| − | | |
| − | See the talk page for more secure alternatives.
| |
| − | | |
| − | === Running Sugar ===
| |
| − | | |
| − | Then, inside the chroot, you can happily run sugar as user 'sugar' with something like
| |
| − | | |
| − | sudo chroot $CHROOT /bin/bash -l
| |
| − | su sugar -
| |
| − | cd ~
| |
| − | ulimit -c unlimited
| |
| − | export DISPLAY=localhost:1
| |
| − | export DBUS_SESSION_BUS_ADDRESS=$(dbus-daemon --session --print-address --fork)
| |
| − | sugar
| |
| − | | |
| − | Then pull up the frame, switch to the home view, and launch some activities!
| |
| − | | |
| − | === Cleaning Up ===
| |
| − | | |
| − | To correctly delete a chroot that you no longer need, kill all processes running in the chroot, and
| |
| − | | |
| − | sudo killall -u sugar
| |
| − | export CHROOT=/path/to/my/chroot # important!
| |
| − | umount $CHROOT/var/run/dbus
| |
| − | umount $CHROOT/proc
| |
| − | umount $CHROOT/dev/pts
| |
| − | umount $CHROOT/tmp
| |
| − | rm -rf $CHROOT
