Description of problem:
I have been trying to build Fedora 35 packages with mock running on an EL8 host.
By default, mock is using systemd-nspawn.
There is an issue with name resolution from within the container.
Same issue with a Fedora 36 buildroot.
However, no issue with a Fedora 34 buildroot.
And indeed, no issue with name resolution on the EL8 host.
After hunting the issue with the fine folks from #fedora-buildsys, I've been instructed to file a bug against systemd, in the hope the issue will be routed to the proper component.
Version-Release number of selected component (if applicable):
systemd-239-45.el8_4.3.x86_64
Not sure which components NVR are relevant, let me know what's needed exactly, I'll fill in the blanks.
How reproducible:
Always
Steps to Reproduce:
1. sudo dnf install mock
2. usermod -G mock <some user>
3. mock -r fedora-35-x86_64 init
Actual results:
fedora 0.0 B/s | 0 B 00:00

Expected results:
no error.
Additional info:
The workaround was to run mock with the '--isolation=simple' option, to avoid using the default '--isolation=nspawn'.
