Such tools are to allow an (ordinary) user to create a root environment within their little bubble WITHOUT affecting anyone else on the system. It all happens within their individual user space. They do NOT get any enhanced privileges.

As I say, within their little bubble only.

For example, they could install a software package within their own 'fake root' and the install routine would be lead to believe that it was installing on the main system but it's not.

installer

installer(1M)						  System Administration Commands					     installer(1M)

NAME

       installer - Solaris Web Start installer utility

SYNOPSIS

       installer [-locales list] [-nodisplay] [-noconsole] [-debug]

DESCRIPTION

       The  installer utility invokes a Web Start install wizard sequence which will lead the user through a sequence of installation panels. This
       installer utility is found on many CDs that are shipped with Solaris and it will be found among the top level files of these CDs.

       When the installer is on a CD being accessed from a desktop file manager, the installer can be double clicked  to  start  the  installation
       sequence. If the user is not currently the system's root user, the root user password will be requested.

       The  installer  utility	can  also  be  run  from  other  UNIX scripts. Usually, a script is used in conjunction with the utility's -nodis-
       play option.  Add the -noconsole option for non-interactive scripts.

OPTIONS

       The following options are supported:

       -locales list   Selects product translations for install, corresponding to the specified list of locales if the specified  locale  transla-
		       tions  are present on the installation media. Locales are supplied in a comma-separated list following the -locales option.
		       An example list would appear as follows:

		       installer -locales fr,de,it

		       This would install products with translations for the French, German, and Italian locales.

       -nodisplay      Runs the install without a graphical user interface. Use the default product install unless it was modified by the -locales
		       options.

       -noconsole      Run  the  install  without any interactive text console device. Useful when paired with -nodisplay for non-interactive UNIX
		       script use.

       -debug	       Outputs extra information about what the install is doing. Mainly for install diagnostic purposes.

FILES

       /var/sadm/install/logs	       location of installation log files
