> In [CASSANDRA-10140], we enabled GC logging by default, since the overhead was low and
asking people providing diagnostics to restart can often make it more difficult to diagnose
problems.
> The default GC log path is set to {{$CASSANDRA_HOME/logs/gc.log}} in {{cassandra-env.sh}},
a directory that is not present in a fresh clone/install. Even if logback creates this directory
later in startup, it is not present when the JVM initiates GC logging, so GC logging will
silently fail for this first Cassandra run
> I haven't tested this in Windows but suspect the same problem may occur. Since lots of
tooling around Cassandra won't create this directory, we should instead consider attempting
to create it in our startup scripts.
