Installing package-installation scripts

The supported package formats, RPM, ipk, and deb, support the addition of installation scripts that can be run at different times during a package installation process. In this recipe, we will see how to install them.

Getting ready

There are different types of installation scripts:

  • Preinstallation scripts (pkg_preinst): These are called before the package is unpacked
  • Postinstallation scripts (pkg_postinst): These are called after the package is unpacked, and dependencies will be configured
  • Preremoval scripts (pkg_prerm): These are called with installed or at least partially installed packages
  • Postremoval scripts (pkg_postrm): These are called after the package's files have been removed or replaced
