In my case, there are dedicated yum repository servers which contain enough packages for fresh install, update and patching. Some packages can be installed without any additional approval process and some are only available through a change request. These servers are highly logged for each package transaction. This is same for Solaris IPS repository servers in our network as well.
Advantage of having package management system is that you do not have to carry around the package (along with numerous dependencies) by FTP/SCP-ing every time you need them to be installed. Of course, the packages available in the repository have to be selected carefully.

We have no telnet client installed! I don't like telnet, but the client is useful for troubleshooting.
Very true especially when you need to be sure if certain port is open on a remote box and you do not have access to nmap.

dtc_install_centos
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.
