As it happens, it does work on the system.

As stated in another response to my messages, the command does require 
to be done with sudo. I tried that, and that works.

The two partitions that I want to be able to mount  at system bootup in 
the Ubuntu system, are sda8 and sda5, as shown in the fstab file above. 
sda5 is the /home partition of my Debian system.

I have not mounted HDD partitions manually. I have only ever mounted 
removable media, like FDD's, manually (and that was a couple of years 
ago, now, I think)

I assume that the command that should be used for mounting the 
partitions manually, is mount.
