The method worked and I was able to get plugins on Gimp 2.9. Thank you very much.
About the CC in replies, it looks like Gmail on phone managed to override that.

Hi Luya,

please put me on Cc in replies, as I don't receive mails from the list, thanks!

I don't know about "easy", but this should work:

- in a terminal, cd to the system plugin folder, e.g. /usr/lib64/gimp/2.0/plug-ins
- identify plug-in files not owned by the gimp package (one line):

  for i in /usr/lib64/gimp/2.0/plug-ins/*; do srcpkg="$(rpm --qf "%{sourcerpm}" -qf "$i" | sed 's|-[^-]*-[^-]*$||g')"; if [ "$srcpkg" != "gimp" ]; then echo "$i"; fi; done

- then symlink these files to the gimp-unstable plugin directory/opt/gimp-2.9/lib64/gimp/2.0/plug-ins/ (or its 32bit equivalent), e.g.:

ln -s /usr/lib64/gimp/2.0/plug-ins/ufraw-gimp /opt/gimp-2.9/lib64/gimp/2.0/plug-ins/

The last command will fail if there's a file with that name in the plug-in directory. Of course you can also link these plugins into your private GIMP directory, "$HOME/.config/GIMP/2.9/plug-ins/".
