You're welcome.

It must be in "man mount" ("man 8 mount"?).

You could also use the "bg" option. If you do use "bg", you might want
to change the "retry=" value because the default is very long.

It is too bad that whoever ported NFS from Solaris (where it was
invented) didn't adopt the Solaris model of having an nfs client
service.

All Linux distributions and versions AFAIK.


Someone suggested using autofs rather than fstab, which seems like
overkill if you have just one nfs server, but that server would be
mounted on-demand, rather than at boot when the network might not yet
be available.
