2 == HOWTO set up a porting dchroot on a debian.org machine ==
4 The script 'upgrade-porter-chroots' has expectations about naming conventions
5 for new porter chroots. The current list it searches for are:
7 lenny squeeze wheezy sid \
8 lenny_i386 squeeze_i386 wheezy_i386 sid_i386 \
9 lenny_amd64 squeeze_amd64 wheezy_amd64 sid_amd64 \
12 Please make sure that new chroots meet the expectations of the script, or update
13 the script accordingly (it lives in the debian.org.git repo)
17 This example is for setting up a $DIST dchroot on paer.debian.org,
20 Do the following as root:
23 echo -n 'Dist: ' && read DIST && export DIST &&
24 echo -n 'Mirror: ' && read MIRROR && export MIRROR
32 debootstrap --keyring /usr/share/keyrings/debian-archive-keyring.gpg --include="apt" --variant=buildd $DIST ./$DIST http://$MIRROR/debian &&
33 cp /etc/hosts $DIST/etc/
36 * enter the chroot and create the chroot tag:
39 echo $DIST > /etc/debian_chroot
41 # change root's .bashrc:
42 grep -q debian.chroot /etc/bash.bashrc || patch /root/.bashrc << 'EOF'
45 +if [ -e /etc/debian_chroot ]; then
46 + debian_chroot=$(cat /etc/debian_chroot)
47 + PS1="[$debian_chroot] $PS1"
53 echo 'Acquire::PDiffs "false";' > /etc/apt/apt.conf.d/local-pdiff
54 echo 'APT::Install-Recommends 0;' > /etc/apt/apt.conf.d/local-recommends
55 echo 'Acquire::Languages "none";' > /etc/apt/apt.conf.d/local-no-lang

59 #*) deploy a policy-rc.d script:
61 apt-get install policyrcd-script-zg2 &&
62 cat > /usr/local/sbin/policy-rc.d << EOF &&
65 # policy-rc.d script for chroots.

73 echo "Not running services in chroot."
79 chmod +x /usr/local/sbin/policy-rc.d
81 #*) install and setup locales and install libnss-db
82 apt-get install locales-all
84 # (if locales-all is not feasible on the machine because of say
85 # disk constraints then install just locales and enable at
86 # least "en_US.UTF-8 UTF-8" and "en_US ISO-8859-1".)
88 #*) setup nsswitch.conf to properly use the ldap stuff
89 # [dchroot]: apt-get install libnss-db &&
90 # sed -i -e 's/^passwd:\[[:space:]]\+compat$/passwd: compat db/;
91 # s/^group:\[[:space:]]\+compat$/group: db compat/;
92 # s/^shadow:\[[:space:]]\+compat$/shadow: compat db/' \
97 apt-get install vim fakeroot devscripts gdb zsh dialog tcsh debfoster
98 # edit the sources.list in the chroot and add contrib/non-free to the
99 # primary source, a security updates source, and deb-src entries for both.
100 # It should end up looking something like
102 echo "deb http://$MIRROR/debian $DIST main contrib non-free"
103 echo "deb-src http://$MIRROR/debian $DIST main contrib non-free"
104 if [ "$DIST" != "sid" ] ; then
105 echo "deb http://security.debian.org $DIST/updates main contrib non-free"
106 echo "deb-src http://security.debian.org $DIST/updates main contrib non-free"
108 ) > /etc/apt/sources.list
109 apt-get update && apt-get upgrade
112 mount -t proc none /proc && debfoster ; umount /proc
119 * [dchroot only] edit /etc/fstab on the system root and add entries to mount /proc and /home
120 in the chroot, there will be existing ones for the other chroots, just copy and
121 adjust. Then mount them (from the system root).

145 * [schroot] set up /etc/schroot/chroot.d/ correctly.
146 [dchroot]: edit /etc/dchroot.conf in the system root, add an entry for $DIST, and update the stable and testing pointers
148 * [dchroot]: run ud-replicate so the new chroot is setup (this would happen via cron eventually, this is just to speed things up)
153 * as a normal user, test that the new chroot works: "dchroot $DIST" or "schroot $DIST", test that the stable and testing pointers work.
