# If the bg option is specified, a timeout or failure causes the mount(8) command
# to fork a child which continues to attempt to mount the export.
# The parent immediately returns with a zero exit code.
# This is known as a "background" mount.
# If the soft option is specified, then the NFS client fails an NFS request
# after retrans retransmissions have been sent, causing the NFS client to return
# an error to the calling application.
# NB: A so-called "soft" timeout can cause silent data corruption in certain cases.
# As such, use the soft option only when client responsiveness is more important than data integrity.
# Using NFS over TCP or increasing the value of the retrans option may mitigate
# some of the risks of using the soft option.
