.`fapolicyd` no longer prevents RHEL updates
When an update replaces the binary of a running application, the kernel modifies the application binary path in memory by appending the " (deleted)" suffix. Previously, the `fapolicyd` file access policy daemon treated such applications as untrusted, and prevented them from opening and executing any other files. As a consequence, the system was sometimes unable to boot after applying updates.
With the release of the https://access.redhat.com/errata/RHBA-2020:5242[RHBA-2020:5242] advisory, `fapolicyd` ignores the suffix in the binary path so the binary can match the trust database. As a result, `fapolicyd` enforces the rules correctly and the update process can finish.
