Richard - are you clear that the permissions are not for the partitions but
for the directories on the mount points on the filing system on which those
partitions have been hung?? This can be hard to grasp, but it can and does
sometimes make a difference, e.g. if the same partition or device gets
mounted somewhere else.
Being slightly older than you, Richard and coming from the pre-electronic
computer generation, I am hoping to grasp and understand the basic Unix
filing system finally some time before I keel over. (I *think* that
electronic computers are slightly older than you are.) ;-)
