I dont agree, hardcoding a value(const) is totally un-desirable IMHO.
But sometimes it's acceptable. (considering how important it's)

Agree whit that, i personally hate NFS/sfs/PVFS/blahblah, no redundancy :)

What do you mean by global filetree? Coda Filetree or local fs filetree?

my intentions are different (as i pointed out some time ago), it's not meant to be easy
for the admin, because an application is going to administrate the data on the volumes,
the app is designed to allow as less human ineraction as possible.

But yes, i understand what you mean about the convenient mountpounts mechanism, and yes,
you're right.

depends, i'm sure most of us have reasons to put /b in /a/b rather than b in /c/b.

Anyway i got the drift! Thanks for the input Ivan.
