The owner field may contain a user name, a question mark (?), or a variable specification. A user name has a maximum of 14 characters and should be a name that already exists on the target system (such as, bin or root). A ? means that the owner will be unchanged as the object is installed, implying that the object of the same name already exists on the target system.
A variable specification can be of the form $Owner or $owner, where the first letter of the variable is either an uppercase letter or a lowercase letter. If the variable begins with a lowercase letter, it must be defined as the package is built, either in the prototype file or as an option to the pkgmk command. If the variable begins with an uppercase letter, the variable specification will be inserted into the pkginfo file as a default value, and may be redefined at install time via a request script. For information on the difference between install and build variables, see "Package Environment Variables".
Files with file type i (information file) and l (hard link) should leave this field blank.
