Does pkg uninstall SUNWexplo/SUNWexplu for Image Packaging System (IPS) do the same as pkgrm SUNWexplo/SUNWexplu does in SVR4?
No, IPS packaging mechanism does not support or invoke any script during pkg uninstall, so pkg uninstall cannot remove the cron job for Explorer automatically. A new command line option, explorer -clean has been provided to uninstall Explorer pkg(5), remove all traces of Explorer including configuration files and cron entry. This command should be run to remove the application completely. For upgrading to a higher version of Explorer pkg(5), removal of configuration files and cron entry are not required.
