Correct - a user can use utilities like pmount, udevil or udisksctl
to mount a partition on a USB stick. For a variety of sticks used
this is probably a good approach (in conjunction with lsblk).

This type of automounting would be closely associated with default
installations of DEs such as GNOME, Xfce, Mate etc. A fvwm user would
have to make an effort to get it.

[Good advice snipped]

Sticking with the desire for an fstab entry, we could could automount
and autounmount using systemd:

Use 'lsblk -f' to get the UUID of a partition on the stick. In fstab:

  UUID=  /media/usbstick auto defaults, noauto,x-systemd.automount,
         x-systemd.idle-timeout=5,x-systemd.device-timeout=1 0 0

(All on one line)

* x-systemd.automount mounts /media/usbstick when any command (such
  as ls) wants to use it.

* systemd.idle-timeout leads to unmounting the partition a specified
  time period after the calling program ceases to access it.

* noauto causes /media/usbstick not to be mounted while the machine is

* x-systemd.device-timeout configures how long systemd should wait when
  no device is plugged in or an incorrect device is found.
