Performing an interim fix mount installation operation

If the -m flag is specified during interim fix installation, the emgr command performs a mount installation operation of the interim fix package.

This means that the existing files that are being fixed are not removed from their present locations. Instead they are over-mounted by the interim fix files. This approach has both advantages and disadvantages. One advantage is that a system reboot unmounts all of the interim fixes. This means that any interim fix that created a serious problem is not mounted after a reboot. The disadvantages are that the administrator must monitor the mount status of interim fixes and some interim fixes may not be removed without a reboot.

The mount installation operation is not supported with interim fix packages that deliver new files.
