Solaris Express Installation Guide: Solaris Live Upgrade and Upgrade Planning

Using the pkgadd -R Command

Packages being installed by using the pkgadd -R option or being removed using the pkgrm -R option must not alter the currently running system. This feature is used by custom JumpStart, Solaris Live Upgrade, non-global zones and diskless client.

Any procedure scripts that are included in the packages being installed with the pkgadd command -R option or being removed by using the pkgrm command -R option must not alter the currently running system. Any installation scripts that you provide must reference any directory or file that is prefixed with the $PKG_INSTALL_ROOT variable. The package must write all directories and files with the $PKG_INSTALL_ROOT prefix. The package must not remove directories without a $PKG_INSTALL_ROOT prefix.

Table B–1 provides examples of script syntax.
