Subject: [PATCH] resolved: Move symlink creation from tmpfiles to daemon
runtime
At least Fedora right now doesn't by default use resolved; the service
is disabled by default in the 90-default.preset file.
The change to unconditionally create the resolv.conf symlink broke
Anaconda and related tools (lorax) which expect it to be a regular
file. In particular, Anaconda expects to be able to persist
networking state from the installation environment to the target
system.
A simple fix is to just have resolved itself create it at runtime.
