dtc_install_centos(8)					      System Manager's Manual					     dtc_install_centos(8)

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.

NAME

       yum-versionlock.conf(5)

SYNOPSIS

       yum-versionlock.conf(5)	is  the configuration file for yum-versionlock(1) Yum plugin for excluding packages that aren't listed in the ver-
       sionlock file.  The plugin will walk each line of the versionlock file, parse out the name and version of the package. It will then exclude
       any  package  by  that  name that doesn't match one of the versions listed within the file (or, optionally, any obsoleter of that package).
       This is basically the same as doing an exclude for the package name itself (as you cannot exclude installed packages), but yum  will  still
       see the versions you have installed/versionlocked as available so that "yum reinstall" will still work, etc.  It can also work in the oppo-
       site way, like a fast exclude, by prefixing a '!'  character to the version.

FILES

       /etc/yum/pluginconf.d/versionlock.conf

FILE FORMAT

       yum-versionlock.conf(5) utilizes configuration options in the form of

       OPTION=VALUE

OPTION

       follow_obsoletes
	      This option is a boolean flag which specifies if the versionlock plugin should look at all the obsoletes, and  see  if  any  of  the
	      packages	specified  have  an obsoleter. If an obsoleter is found then all versions of that package will be excluded. This option is
	      off by default, as yum-versionlock(1) will take some time to do the obsoletes processing, and for non-rename  obsoletes  any  issues
	      you had which kept you at a specific version of a package should be different with another package.

OPTION

       locklist
	      This  option  is a string with points to the file which will have the versionlock information in it. Note that the file has to exist
	      (or the versionlock plugin will make yum exit). However it can be empty.
