Used with the -s option, it reads the package to a spool directory instead of installing it. Certain unbundled and third-party packages are no longer entirely compatible with the latest version of pkgadd . These packages require user interaction throughout the ins- tallation and not just at the very beginning. TRUE pkgadd will permit keyboard interaction throughout the ins- tallation as long as this environment variable is set.
Installation occurs in non-interactive mode.
The default mode is interactive. The token none overrides the use of any admin file, and thus forces interaction with the user. Unless a full path name is given, pkgadd first looks in the current working direc- tory for the administration file. Identify a file or directory which contains output from a previous pkgask session. The token all may be used to refer to all packages available on the source medium.
