how to download static rpms for production centos

gistfile1.txt

def production centos has no connection to internet except serving port
background production machine was not set up by you, hence you need to perform addtional setup.

1. get a replica of production centos and connect it to internet
2. `repotrack emacs -u |xargs wget`

exception:

if architecture differs, e.g. i386 local but x86_64 in production, you can do

    repotrack emacs -u > emacs.txt
    cat emacs.txt|sed -e "s/\/i386\//\\/x86_64\//" -e "s/\.i686\.rpm/\.x86_64\.rpm/" > emacs-x86.txt
    cat emacs-x86.txt|xargs wget
    
or in one liner:

    repotrack emacs -u |sed -e "s/\/i386\//\\/x86_64\//" -e "s/\.i686\.rpm/\.x86_64\.rpm/" |xargs wget
    
3. copy rpms to production centos and do `rpm -Uvh emacs....(dependent packages only)`. you may not need to install all rpms but you do not want to miss one as you will need to copy back and forth.
