How do I configure swlist to not display superseded
A new option to swlist, "show_superseded_patches", was introduced in
11.00 via the SD-UX cumulative patch PHCO_20078. In 11.00, by default,
swlist displays all installed patches, including superseded ones. In
11.10+, by default, swlist does not display superseded patches.
Assuming you have PHCO_20078, or any more recent SD-UX cumulative
patch installed, you may change the default behavior of swlist in 11.00.
To do so, add the following line to the file /var/adm/sw/defaults:
swlist.show_superseded_patches = false
