Hi,

Clever workaround! What are now the performances on previous examples
(same profiles and same packages)?

Hum? Interesting… well weird! If it is not a “morphism” then it is not
really an updater. Anyway.
I am curious about the comparison:
time(update-mime-database(X ∪ Y))
vs
time(update-mime-database(X)) + time(update-mime-database(Y))
vs
time(update-mime-database(X ∩ Y))

’shared-mime-info’ is simply a package, right? So what does it means:
«Find a way to avoid reprocessing 'shared-mime-info'» in:
--8<---------------cut here---------------start------------->8---
;; the database. TODO: Find a way to avoid reprocessing
;; 'shared-mime-info', which is the most expensive one.
[...]
(invoke #+(file-append shared-mime-info
"/bin/update-mime-database")
destdir)))))))
--8<---------------cut here---------------end--------------->8---
? Well, I miss why and how ’shared-mime-info’ could be the culprit here
or what could be improved with “shared-mime-info”? Maybe replace the
“lazy reference” by a strict one if it makes sense.
All the best,
simon
