# MSP360's pre-flight check does `mountpoint <Path>` on the exact configured
|

# storage Path (/mnt/nas-backups/MSPBackups). Since that's a subdirectory of
|

# the real CIFS mount (/mnt/nas-backups), it never registers as a mountpoint
|

# on its own -- so we bind-mount it onto itself to make it one.
