In this tutorial, we learn how to install rpm installation into a specific directory. For that to happen, rpm package should be relocatable.
If that package is not flexible enough (--prefix path can't be set) to be installed in to a different locations as provided by the user or it's hardcoded, examples are like bash shell package or flash packages, which may not be relocatable.
Not relocatable Package
Let me start with examples where the rpm package is not relocatable, ie cannot install into a specific directory.
$sudo rpm -qpi /home/redhat/Downloads/flash-plugin-22.214.171.124-release.i386.rpm Name : flash-plugin Relocations: (not relocatable) Version : 126.96.36.199 Vendor: Adobe Systems Inc. Release : release Build Date: Fri 10 Aug 2012 06:45:38 PM PDT Install Date: (not installed) Build Host: frbld_lnx_016.macromedia.com Group : Applications/Internet Source RPM: flash-plugin-188.8.131.52-release.src.rpm Size : 18383579 License: Commercial Signature : (none) Packager : Adobe Systems Inc. URL : http://www.adobe.com/downloads/ Summary : Adobe Flash Player 11.2 Description : Adobe Flash Plugin 184.108.40.206 Fully Supported: Mozilla SeaMonkey 1.0+, Firefox 1.5+, Mozilla 1.7.13+
So the above package is not relocatable and it can’t be installed in a custom location.
You can also try below command to find whether the package is relocatable
$sudo rpm –qi [package_name] | grep Relocations
If the package is relocatable it might show in the output as below
Name : keyutils-libs Relocations: /opt
Install package to a different directory
If the package is relocatable, it can be installed to a different location with
$sudo rpm --prefix=/mnt gnome-backgrounds-2.28.0-2.el6.noarch.rpm
