NFS, thou shamest me

I don’t know why I always forget this.  I’ll get on a brand-spanking new server that I have somewhere, and I’ll have to NFS mount something.  I’ll make sure that I am running the right command, that my options are all correct, that my incantations are all in line… auto,nfsvers=3,exec,bg,intr,rsize=32767,wsize=32767,tcp,user, nonsense, nonsense, nonsense… only to find that my mount command hangs.

Why oh why must NFS hang so when I try to mount it?

And then, dmesg to the rescue… some idiot forgot to turn the portmap service on the machine.  *sigh* alas, I am that idiot.

So many leaky abstractions, so little time.
