[pca] Tweaking patchdiag.xref

[Martin Paul]

Hi Sergio,

I don't have a straight solution for your task, but here are some ideas:

 > 1) Is there any better way to do it?

Try using "pca --minimal missingr". The "minimal" option will make PCA 
work with the list of patches in the Recommended Patch Set. So this 
command should give you a list of missing applicable patches. When 
feeding PCA an empty "showrev" output (simulating an unpatches system), 
you should get the complete number of applicable patches.

> 2) is pca considering that info (field #10)?

yes, it uses it to determine whether a patch is applicable or not.

> 3) If yes, does anybody have any tip where can I extract that info from?

besides patchdiag.xref? The "VERSION" line in the <pkg>/pkginfo files, 
to be found in the extracted patch zip file.

> 4) Did anybody have a requirement like this before? (compare against a fixed set of patches)

Not me.

hope it helps,
Martin.
