How to create chroot environments

You might have a look at rpmstrap or other bootstrapping methods, however I have simply used a free VMware server to create the initial image.

SLC3

    
    booting from SCL3-i386-boot.iso
    default install
        Text based Internet
        Development Tools
        System Tools
        hostname: slc3-chroot
    root password is 'root'
    # installing some extra packages:
    cd /etc/apt/sources.list.d
    vi cernonly.list
        enabling     
    vi dag.list
        enabling
    apt-get update
    apt-get dist-upgrade
    apt-get install ccache
    # various documentations:
    apt-get install docbook-utils docbook-utils-pdf psutils docbook-style-xsl ghostscript
    # that one can login using 'ssh -X':
    apt-get install XFree86-xauth
    # for convenience:
    apt-get install vim-X11 vim-enhanced vim-common
    # and Java
    rpm -ivh jdk-1_5_0_02-linux-i586.rpm

Creating the initial tarball:

   ssh root@10.10.10.5 'cd /; tar -cpzf - bin dev lib sbin var boot etc initrd misc opt root usr home' >SLC3-chroot-master-2007-03-06.tgz

SLC4

Installing SLC4:

    booting from SCL4-i386-boot.iso
    default install
        Text based Internet
        Development Tools
        System Tools
        hostname: slc4-chroot
    root password is 'root'
    # some packages to be installed:
    yum upgrade
    yum install ccache screen
    vim /etc/yum.repos.d/cern-only.repo
        enabled=1
    # gLite ant build backward compatibility and Java components:
    yum install java-1.5.0-sun-devel java-1.5.0-sun xorg-x11-deprecated-libs
    # various documentations:
    yum install docbook-utils docbook-utils-pdf psutils docbook-style-xsl ghostscript
    # simlifying ETICS client install:
    yum install pyOpenSSL python-log4py PyXML
    # that one can login using 'ssh -X':
    yum install xorg-x11-xauth
    # for convenience:
    yum install vim-X11 vim-enhanced vim-common

Creating the initial tarball:

    ssh root@10.10.10.4 'cd /; tar -cpzf - bin dev lib sbin var boot etc initrd misc opt root selinux usr home' >SLC4-chroot-master-2007-01-31.tgz

SLC5

     # Update of a minimal SL5 installation:
     yum groupinstall 'Development Tools'
     # for ETICS:
     yum install -y python-devel
     yum install -y pyOpenSSL python-log4py PyXML
     # for VOMS:
     yum install -y docbook-utils docbook-utils-pdf psutils docbook-style-xsl ghostscript transfig libxslt
     # for gSOAP
     yum install -y bison bison-devel libtool

     # Hidden build dependencies deduced from the ETICS build nodes:
     # http://eticssoft.web.cern.ch/eticssoft/internal/public/VMWareImages/
     yum install -y glib2-devel libxml2-devel openssl-devel curl-devel expat-devel
     yum install -y apr-devel apr-util-devel httpd-devel
     chkconfig --del httpd
     yum install -y boost boost-devel libstdc++ libstdc++-devel
     yum install openldap-devel
     #  missing dependency: openldap???
     rpm -q openldap
         openldap-2.3.27-8.el5_2.4
     # openldap-devel is for the older version: 2.3.27-8.el5_1.3
     # so I have to downgrade.
     rpm --nodeps -e openldap
     yum install openldap-2.3.27-8.el5_1.3 openldap-devel-2.3.27-8.el5_1.3

    # The 'yum groupinstall' step has probably installed a number
    # of unnecessary packages, so it could be improved.


    # add user bob
    adduser -m bob
    cp -r /root/.ssh /home/bob
    chown -R bob:bob /home/bob/.ssh

    # not *strictly* necessary, but...
    yum install -y vim-enhanced
    yum install -y screen

    # to install ccache enable dag repo. Also, no linuxsoft mirror yet: use the "true" repository...
    cd /etc/yum.repos.d/
    vim dag.repo
        enabled=1
        baseurl=http://apt.sw.be/redhat/el5/en/$basearch/dag
    
    yum install -y ccache

# as bob:

    # edit .bashrc
    vim .bashrc
        export ETICS_HOME=$HOME/etics
        export WS=$HOME/build
