This may be expected behavior, but say you have a symbolic link on one qnx
file system on one machine (call it machine ‘a’) such as:
home->/fs/hd0-qnx4-2/home
and you have the same thing on machine ‘b’
If on machine ‘b’ you type:
ls /net/a/home
that will resolve to the /fs/hd0-qnx4-2/home on machine ‘b’, not machine
‘a’.
This is understandable…and clear to me why this happens…just caught me
off guard. I couldn’t figure out why the files I was copying weren’t being
put where I wanted them. 
Now my link is:
home->fs/hd0-qnx4-2/home
Is this how qnx4’s FLEET would have handled it?
Just some musings,
Kevin

Yes. The leading slash always represnt your root of local machine.
That’s why you need to link relative path, instead of absolute path,
if you want to access cross QNET.

Nope, QNX4 has the node numer in the symbolic link.

Yes and no. There was a great debate over whether symbolic links
should be resolved relative to where they lived, or relative to the
network root of the person (process) looking at them.
If I remember correctly, the choice on the behaviour actually changed
at one point – from doing it one way, to doing it the other.
To be careful under QNX4, one usually did something like:
home->//5/fs/hd0-qnx4-2/home

It is always interesting to hear about the history of decisions in a design.
You know, this has some relation to Robert Krten’s QNET Proxy idea (see
advocacy). If the request to open a file was resolved on the node where the
filename existed, it would behave differently wouldn’t it?.
Just my musings, once again.
