 Does `findmnt` show the same? Also, is your /etc/mtab a regular file,
 or a symlink to /proc/self/mounts?

thanks
i had overlooked this and this has fixed  the  phantom mount point problem

 Make sure you have USB mass storage drivers enabled (compiled in or
 modules).

I have   usb-mass-storage compilrd in  the kernel

but  it refuses to generate a file in /dev when a usb  'stick'  -any usb-flash 
-memory device  is plugged in.  BUT it  generates a /dev file when  a hard 
disk in an eclosure with a usb interface is plugged in

This isn't a systemd problem, its about the kernel's response to the 
insertion and the policy for dealing with it.


Watch (with tail -f) your syslog file for something like this


Aug  5 12:03:29 MainBox kernel: [17000.745038] usb 1-8: new high-speed 
USB device number 6 using ehci_hcd
Aug  5 12:03:30 MainBox kernel: [17001.554699] usb 1-8: New USB device 
found, idVendor=058f, idProduct=1234
Aug  5 12:03:30 MainBox kernel: [17001.554705] usb 1-8: New USB device 
strings: Mfr=1, Product=2, SerialNumber=0
Aug  5 12:03:30 MainBox kernel: [17001.554708] usb 1-8: Product: Mass 
Storage Device
Aug  5 12:03:30 MainBox kernel: [17001.554711] usb 1-8: Manufacturer: 
Alcor Micro


I have my udev rules set to recognise that idVendor and idProduct and 
mount automatically, when I insert that stick AFTER BOOT, in 
/var/run/usr/anton, though this is configurable - see the documentation 
on udisks2.  Some people prefer to have it at /media/.  The list of what 
to do with various idV/idP is there somewhere but I forget where.


In short:

1. this is not a systemd issue.
2. it is a udev issue
3. it is all configurable
4. the configuration tables determine what goes where
