[Yum] _rpm.error: rpmdb open failed

[Russell Jones]

Hi all,

Can anyone assist me with understanding what the below error means? This 
occurs when doing a "yum install" into a rootdir with CentOS 5 packages 
on a CentOS 6.4 server. This only occurs specifically with CentOS 6.4, 
if I do the exact same command on CentOS 6.3 it works fine. Thank you in 
advance for the help!
