New subject: Trying to rebuild grub2-2.06-2.fc34 from source rpm, but one subpackage is not built.

24 Jul 2021


      Hello everyone!
I am trying to apply a patch to grub2-2.06-2.fc34 and to make a package out of it. To do so I'm using fedpkg for the most part, but when I come to the point of building the package with "fedpkg local" one of the subpackages seems missing: grub2-pc-modules.noarch
This unfortunately makes impossible to replace the whole grub package set with the newly compiled packages, as dnf rightfully complains the missing one (see below for installed vs built packages).
Weirdly enough, searching for "pc-modules" among the rpm source files does not return any result, while searching just "modules" shows some code used to build other packages (such as grub2-efi-x64-modules). It doesn't look like anything related to "pc-modules" exists in the code in the first place.
Is there something I am not doing right? I can see other .noarch subpackages are built just fine in the process.
Thanks to anyone who can help me clear this up :)
Here's a list of the grub2 related packages on my system (fresh fedora 34 installation):
```
[michele@tre grub2]$ dnf list --installed | grep grub2
