USB mount

If a filesystem in /etc/fstab has a noauto entry, can that filesystem only be mounted manually using the mount command or
is there any chance that it will be automatically mounted by
usbmount ?

The filesystem is used in a USB port.

why don't you try it? That would be much faster.....

It now seems to me that the situation is as follows :-

Filesystems in /etc/fstab which have the noauto option are not automatically mounted at boot time, so if these filesystems are already
plugged into USB ports at boot time, they would subsequently have to be manually mounted in order to be used.

Filesystems which are plugged into a port after the system has been booted are automatically mounted.

That is configured differently on different systems. It's easy enough to change the behavior, either to automount or not to automount.

external usb sticks are usually not listed in /etc/fstab and therefore automounting is not configured that way.

But of course you can always add them in if you want to.

Not usually, but it certainly happens. I'm posting from a former chromebook with a 16GB internal SSD, and using a mini USB drive for /home, which stays in the USB3 slot, because I need the storage space. That drive is in fstab because it needs to be. I also have a NFS server which is also my main desktop which has 3 external USB drives in fstab, for insuring they are mounted to the same place every time. There are valid reasons for putting some USB drives in fstab.
