[ILUG] Merging directories transparently

[David Neary]

Hi all,

I have something that isn't necessary, but that I'd *like* to do,
if possible (I think it should be possible, from my limited
knowledge of filesystems).

I have two directories - one of which is on a filesystem which is
full, the other which has quite a bit of space - which I would
like to have appear in one directory transparently. In other
words, I want to see all the files in /mnt/archive/src (say) when
I cd into /usr/local/src (say). Different partitions, so hard
links isn't an option. Symlinks would do the job, but the option
I'd prefer (if it were possible) would be to have real files in
the same directory from two different filesystems, transparently. 

Is it a fool's chase? Is this impossible, or is there some
funniness that I can do? Or will it be cd $dir1; for i in
${dir2}/*; do ln -s $i .; done?

Dave.
