If I'm installing Monitor (agent) on an OES2 Linux server, I am prompted for the path to a domain directory

But this server is not going to have any domains on it.

the docs are poor at best on this section (other than to follow the prompts)

I am assuming (since there's a "file browser" button) that if there's no domain on this server, that I cannot use a UNC path and must use a mount point to a server that has a domain?

And if the other server is on NSS, I will need ncpmount?
