making a directory tree:

[Joseph C. Lininger]

Hello,
To my knolege, there is no way to make the contents of several
directories appear as if they are in one directory. For example, you
couldn't mount several iso images as you say and then have all of their
contents appear in one directory. (But see my proposed solution later)
There are several reasons for this, one of which has already been
pointed out by another list member (name conflicts). There are other
technical reasons that the system as it stands at the moment doesn't
support this. You must access each of the volumes separately.

You do have one option if you can be absolutely sure there will be no
named conflicts. Let's say you have the first image mounted on /mnt/iso1
the second on /mnt/iso2 and the third on /mnt/iso3. You could create one
directory, say in /home/jbahm/isos or something and place a symbolic
link to every file in there, like this:

cd /home/jbahm/isos
ln -s /mnt/iso1/* ./
ln -s /mnt/iso2/* ./
ln -s /mnt/iso3/* ./

You could probably also get away with:

ln -s /mnt/iso*/* ./

to do it all at once, but haven't tried so can't be absolutely sure.
Again, you must take care that there are absolutely no name conflicts.
It won't be pretty if their are.

Equal causes can produce very unequal effects.
