VERIFIED SOLUTION i

In MailStream Plus 8.3.1 and later, the UNIX/Linux 'install' script no longer makes ownership changes (using the 'chown' command)

Operating System: UNIX/Linux

Configuration: MailStream Plus 8.3.1 and later
 
With MailStream Plus 8.3.0 and earlier, in the 'install' script it would ask if changes should be made to the ownership of the files/folders during the installation.

Beginning with the MailStream Plus 8.3.1 release, the install script no longer will ask about, nor make those changes.

If ownership changes are needed, they now need to manually be done outside of the installation process.

The comment box at the beginning of the install script does mention about making needed permission changes-
# In addition, the area where this product is installed MUST have the            #
# proper user:group permissions.                                                 #
#                                                                                #
# chown -R <user:group> /opt/pb/<product>                                        #
# chmod -R 775 /opt/pb/<product> 



And the MailStream Plus Installation Guide mentions it as well, at the end of the Product install section-
6. After you load the files, you may need to change the owner and group of each file using the chown command:
chown -R owner:group *
Change owner to your owner name, and group to your group name. The asterisk (*) updates all of the files and directories, and switch -R updates all of the subdirectories. You may change file permissions to limit or expand access to product files; however, this is not required.
If you have any MailStream Plus add-on products, repeat this step for each one.
