How to update/remove a file in a Solaris 11 custom ips pkg?

Hi,

We have our own custom ips pkg, and we are trying as part of an pkg update to remove some files

As for a normal pkg manifest would look somthing like below, I was not able to found in the docs how to specify in an updated manifest that removes some of the files.

For example

mypkg manifest looks like this

-------------

set name=pkg.fmri value=pkg://solaris/application/mypkg@1.0,5.11-0

set name=pkg.summary value="MyPkg"

set name=description value="MyPkg"

set name=variant.arch value=i386

depend fmri=pkg:/diagnostic/top type=require

dir group=sys mode=0755 owner=root path=opt
