• Control scripts delivered with the patch fileset run only when that
patch fileset is installed. They do not replace the control scripts for
the base fileset.
See “Fileset Specification” on page 331 for a complete description of all
patch and non-patch fileset attributes.
Patch fileset attributes include attributes that you can specify in a
product specification file (PSF) and attributes generated by SD.
User-specified Attributes
You can specify the following patch fileset attributes in a PSF:
• ancestor
software_specification
Designates the base fileset to be patched.
• supersedes
software_specification
Used when a patch replaces an earlier patch. The attribute indicates
which previous patches are replaced by the patch being defined. This
attribute is repeatable.
This attribute consists of a list of software specifications of other
patch filesets that the patch supersedes:
supersedes
product . fileset ,fr= revision
When a patch supersedes another patch, the superseding patch is
automatically selected by default. A superseding patch replaces the
files of the patch it supersedes when installed after that patch.
Patches may supersede other patches to the same base (non-patch)
fileset, or they may be applied to the same base fileset in parallel
with other patches.
