My understanding of how soft dependencies works is that file system
metadata is cached in memory for a short period of time (like 20
seconds?), which means it's at risk (of being lost) if the machine were to
loose power. The mount man page also says that it's gone through "moderate
to heavy testing, but should still be used with care."
