Hi Pierre,
Yes, of course you are right. Packages are installed once and then reused in different profiles (AFAIK). I just did not give much thought to it at the moment. Supporting multiple profiles in a package can be a real pain, right? I mean, there is no magic bullet. In the case of fontconfig, we have the ability to modify the fonts.conf in order to add more font paths. As for other programs, there is usually a way, but it is not universal.
Of course, the hammer solution would be to shove a package going into a different profile into a different store entry (under assumption that at the build-time the package takes -p option as the default). Perhaps something like that could be offered as an option to users? Maybe this is even possible now? I have not done any research on it.
On the other hand, I have not seen any real "official" endorsement of multi-profile setups by Guix as a project :) .
Cheers,
T
