Server component creates paths relative to server content dir f.e.
https://github.com/wildfly/wildfly-core/blob/main/server/src/main/java/org/jboss/as/server/deployment/module/DeploymentRootMountProcessor.java#L60
This is supposed to be special directory, but this is not the case. F.e. VFS doesn't know anything about it which may lead to errors.
