NAME

       dtc_install_centos - bootstrap a CentOS install to use in a chroot or VM

SYNOPSIS

       dtc_install_centos <install root> <yum environment>

DESCRIPTION

       This shell script is part of the dtc-xen package, generally to be used by the dtc panel to
       install a new a Xen VPS server. This script is called by dtc_reinstall_os  when  the  user
       chooses to install the CentOS operating system.

       How it works: it generates a temporary yum configuration in the yum environment directory,
       that directs yum to act inside the install root instead of in the  base  system;  then  it
       kindly  requests  yum  to install the basesystem, centos-release and yum packages onto it.
       Yum then uses the configuration  to  download  the  required  (usually,  security-updated)
       packages and then perform the RPM installation process under the install root.

       It  requires  both  RPM  and  yum.   It does work under Debian (it was developed in Ubuntu
       first).  It should also work on RPM-based systems without destroying the  system-wide  RPM
       and yum configurations.

OPTION

       <install root>

       Target directory where CentOS will be deployed.  Must exist beforehand.

       <yum environment>

       Directory  where  yum  will  store  the  repository  manifests and configuration.  Will be
       automatically created.  Cached RPMs and manifests will be left, as usual, in  a  directory
       var/cache/yum inside the install root.

EXAMPLE

       dtc_install_centos /root/yum /xen/13

       This  will  setup the operating system in /xen/13, with the CentOS configuration folder in
       /root/yum.

BUGS

       It's limited to CentOS 5 at the moment.

       It must be run as root.

       Under some circumstances, the installation process itself may kill  processes  running  on
       the  host machine.  The chroot yum does should be sufficient to avoid this, but we haven't
       been able, yet, to ascertain why this fails sometimes.
