Summary:                    Saving of admin file still doesn't work correctly
Description: 
On an update with
  pkgutil -U -u -y
I got after some package updates the error

...
Installation of <CSWpmipcshrlite> was successful.
Removing old version of CSWpmiozlib
pkgrm: ERROR: unable to open admin file </var/opt/csw/pkgutil/admin.run>:
No such file or directory

Removal of <CSWpmiozlib> failed (internal error).
No changes were made to the system.

pkgadd: ERROR: unable to open admin file </var/opt/csw/pkgutil/admin.run>:
No such file or directory

The error was with this version:

I think (hope) that it was the second instance that caused the problem.
Maybe some kind of lock system is necessary?
