common home directory /etc/passwd NFS shared across multiple linux systems


I am running SLES 11.3. would the following pose a problem (irregardless of operating system) and if so how/why.

system A : home directories are under /data/users/<account name>
system A : share out /data via NFS server

System B/C/D: NFS mounts system A:/data to /data. Everyone's user account on here is /data/user/<account name> which is technically from system A.

if a user logs into systems A, B, C, D at the same time and does stuff, what problems would that cause?

No problem with desktops and applications is known. (Well, there was a problem with older Gnome and different architectures SPARC and X86 - different byte order).
Certain applications like Firefox set a lock file in the home directory and allow only one instance on one system.

I think that /home/<account name> is widely used as homedir path, so consider /home as a mount point (on system A you can use an NFS mount or a bind-mount). If you use automounter, you can use common settings on all systems - if not, you might need to disable the autofs service.

If the user decides to manipulate the same file(s) on each system, you could potentially end up with each system stomping the other's modifications. many programs will warn the user that a file on disk has changed, others will not.
