For example, a vendor +may distribute their software to install in "/opt" but you'd like +it to install in "/usr/opt". If the vendor were distributing a +relocatable RPM package, it would be easy. + +\section relocatable_building Building a Relocatable Package + +Not all software can be "relocatable". Before continuing you should +think about how the program works, what files it accesses, what other +programs access *it* (and expect it to be in a certain place), etc. +If you determine that the location of the package doesn't matter, +then it can probably be built as "relocatable". + +All you need to do to build a relocatable package is put one or more: + +\verbatim + Prefix: <dir> +\endverbatim + +in your spec file. The "<dir>" will usually be something like "/usr", +"/usr/local", or "/opt". Every file in your %files list must start +with that prefix. For example, if you have "Prefix: /usr" and your +%files list contains "/etc/foo.conf", the build will fail. The fix for +this is to put + +\verbatim + Prefix: /usr + Prefix: /etc +\endverbatim + +into the spec file so that the /usr and /etc directories may be +relocated separately when this package is installed. + + +\section relocatable_installing Installing Relocatable Packages + +By default, RPM will install a relocatable package in the prefix +directory listed in the spec file. You can override this on the +RPM install command line with "--prefix <dir>". For example, if +the package in question were going to be installed in "/opt" but +you don't have enough disk space there (and it is a relocatable +package), you could install it "--prefix /usr/opt". + +If there is more then one Prefix you may relocate each prefix +separately by using syntax like: + +\verbatim + rpm ... --relocate /opt=/usr/opt --relocate /etc=/usr/etc ... +\endverbatim + +If any of the Prefixes is not being relocated they can be skipped on +the command line + +*/ |
