NFS issue with OSX (not lion) and NV+

So it works

Ummm... So why not before? Or maybe it doesn't matter...

I'd like to know whether or not it's possible to make finder remind this share, so when i get back home, it automatically detects it's there and adds it to the Finder list.

Not really - we're back to my original comment that NFS works differently than CIFS/AFP; the "use model" is different.

All file sharing protocols are designed such that multiple users of a host computer can access shares, as well as allowing multiple hosts to access the shares. But to more easily illustrate a key difference, consider just the former - one shared host (your Mac) with multiple user accounts each accessing shares on a NAS

Under AFP/CIFS, each user individually mounts each share separately - authenticating with their username/password each time which registers which user is then accessing the share and determines access rights and permissions.

Under NFS, shares are typically mounted only once at a fixed predefined path and all users access the same path. User permissions are determined based on the UID number associated with the account rather than each user authenticating via username/password

The difference has major implications for file sharing, but also for how shares are typically mounted. For an NFS share to always be available you mount it once (at boot, or on access) to a specific path, and then simply access that path via finder as if it was a local folder. That's where services like autofs come in, automatically mounting the share on demand at the predefined path.

Would you recommend any changes to this setup?

Possibly related to permissions & access rights, but it is heavily dependant on your ultimate needs. Again I'd recommend some general reading if you're not familiar with how NFS controls access and permissions.
