It would be nice to pass multiple actions to a checkIf method , the same way as a check allows through the comma.

.check(
   checkIf("${first.exists()}")(do_first),

it would be nice to have API as follows:

check(checkIf("${first.exists()}")(do

The idea is to be able to write the following to override the log configuration in dev-mode.

lagomDevSettings ++= Seq(
  "logger.resource" -> "logback-dev.xml"
)

During akka-grpc-maven-plugin:0.6.0:generate, and likely other similar non akka-grpc tasks, if /tmp/ for this process is not accessible, or has the noexec mount option set:

Perhaps add a fal
