804  * Name:	doRemove

806  *		or more non-global zones.
807  * Arguments:	a_nodelete: should the files and scripts remain installed?
808  *			- if != 0 pass -F flag to pkgremove - suppress
809  *			the removal of any files and any class action scripts
810  *			and suppress the running of any class action scripts.
811  *			The package files remain but the package looks like it
812  *			is not installed. This is mainly for use by upgrade.
813  *			- if == 0 do not pass -F flag to pkgremove - all
814  *			files and class action scripts are removed, and any
815  *			appropriate class action scripts are run.
816  *		a_altBinDir - pointer to string representing location of the
817  *			pkgremove executable to run. If not NULL, then pass
818  *			the path specified to the -b option to pkgremove.
819  *		a_longestPkg - length of the longest package "name" (for
820  *			output format alignment)
821  *		a_adminFile - pointer to string representing the admin
822  *			file to pass to pkgremove when removing a package from
823  *			the global zone only. Typically the admin file used for
824  *			the global zone is the admin file passed in by the user.
825  *			If this is == NULL no admin file is given to pkgremove.
826  *		a_zoneAdminFile - pointer to string representing the admin
827  *			file to pass to pkgremove when removing the package
828  *			from a non-global zone only. Typically the admin file
829  *			used for non-global zones supresses all checks since
830  *			the dependency checking is done for all zones first
831  *			before proceeding.
832  *			A zoneAdminFile MUST be specified if a_zlst != NULL.
833  *			A zoneAdminFile must NOT be specified if a_zlst == NULL.
834  *		a_zlst - list of zones to process; NULL if no zones to process.
835  * Returns:	int	(see ckreturn() function for details)
836  *		0 - success
837  *		1 - package operation failed (fatal error)
838  *		2 - non-fatal error (warning)
839  *		3 - user selected quit (operation interrupted)
840  *		4 - admin settings prevented operation
841  *		5 - interaction required and -n (non-interactive) specified
842  *		"10" will be added to indicate "immediate reboot required"
843  *		"20" will be added to indicate "reboot after install required"

1630  *			- if != 0 pass -F flag to pkgremove - suppress

1632  *			and suppress the running of any class action scripts.
1633  *			The package files remain but the package looks like it
1634  *			is not installed. This is mainly for use by upgrade.
1635  *			- if == 0 do not pass -F flag to pkgremove - all
1636  *			files and class action scripts are removed, and any
1637  *			appropriate class action scripts are run.
1638  *		a_altBinDir - pointer to string representing location of the
1639  *			pkgremove executable to run. If not NULL, then pass
1640  *			the path specified to the -b option to pkgremove.
1641  *		a_adminFile - pointer to string representing the admin

1643  *			If this is == NULL no admin file is given to pkgremove.
1644  * Returns:	int	(see ckreturn() function for details)
1645  *		0 - success
1646  *		1 - package operation failed (fatal error)
1647  *		2 - non-fatal error (warning)
1648  *		3 - user selected quit (operation interrupted)
