YES ! You surely know that some use-flags can also be set for individual packages (and not globally; e.g. for some time this was true for use-flag "wayland"). You will get all these now automatically with your combined profile. Peter

Following the post I created the local profile 'hardened-desktop' and confirmed the USEs are the combination of the two profiles. I suppose the added benefit of this new profile is that it will inherit the changes eventually done to the parent profiles by the gentoo developers, correct? P.S.: Maybe read also the first note from this article: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Kernel_Hardening_with_KSPP Thanks, this requires a bit more of study on my side which I'll certainly do as a second step. BTW, hardened-sources is no longer available so KSPP might be the only option. raffaele

These days the hardened profiles don't add much. The main thing they "add" is the lack of unnecessary features enabled by default in a desktop profile. It's a tedious process, but turning on the features you need one at a time in package.use will eventually result in a smaller attack surface than enabling them all at once in the desktop profile's make.defaults. Of course you could do that the other way around, too, starting from a desktop profile and disabling them one at a time.
