Currently, if the linux service is run twice, mount(8) fails with:
mount: linprocfs: Device busy
mount: linsysfs: Device busy
mount: devfs: Device busy
mount: fdescfs: Device busy
mount: tmpfs: Device busy
It is a bit more user-friendly if before running mount(8) the service
checks if there are any file systems left to be mounted. This patch
implements this behavior.
Also, while here, create mount points directories (as suggested by
otis).
