Don,
Thanks a lot for the detailed explanation and background information!
That's something I can quote in the future. Maybe you could ask Gerry to
publish it in his patch blog as well.
Patches such as these will typically contain code in the patch's prepatch
> script in order to prevent the patches being applied on top of the
wrong OS.
And this is exactly what I usually duplicate in pca's set_extra_req()
and chk_extra_req() functions to fix such issues.
In a perfect world, there would be a formal language to desribe such
extra requirements which would be included in patchdiag.xref. Then one
source could be used both by a patch analysis tool and by patchadd,
turning this into a non-issue.
I understand that this was a reason for smpatch's "realizations", but
the concept wasn't taken far enough and/or the implementation was
suboptimal.
Martin.
