+@cindex RPM, build an RPM archive with guix pack
+This produces an RPM archive (a package with the @samp{.rpm} file
+extension) containing all the specified binaries and symbolic links,
+that can be installed on top of any RPM-based GNU/Linux distribution.
+The RPM format embeds checksums for every file it contains, which the
+@command{rpm} command uses to validate the integrity of the archive.
+
+Advanced RPM-related options are revealed via the
+@option{--help-rpm-format} option. These options allow embedding
+maintainer scripts that can run before or after the installation of the
+RPM archive, for example.
+
+The RPM format supports relocatable packages via the @option{--prefix}
+option of the @command{rpm} command, which can be handy to install an
+RPM package to a specific prefix, making installing multiple
+Guix-produced RPM packages side by side possible.
+
+@example
+guix pack -f rpm -R -C xz -S /usr/bin/hello=bin/hello hello
+@end example
+
+@example
+sudo rpm --install --prefix=/opt /gnu/store/...-hello.rpm
+@end example
+
+@quotation Note
+Similarly to Debian packages, two RPM packages with conflicting files
+cannot be installed simultaneously. Contrary to Debian packages, RPM
+supports relocatable packages, so file conflicts can be avoided by
+installing the RPM packages under different installation prefixes, as
+shown in the above example.
+@end quotation
+
+@quotation Warning
+@command{rpm} assumes ownership of any files contained in the pack,
+which means it will remove @file{/gnu/store} upon uninstalling a
+Guix-generated RPM package, unless the RPM package was installed with
+the @option{--prefix} option of the @command{rpm} command. It is unwise
+to install Guix-produced @samp{.rpm} packages on a system where
+@file{/gnu/store} is shared by other software, such as a Guix
+installation or other, non-rpm packs.
