Or use -d with daemontools, that's pretty much the intended purpose.
The thing is, watch out for binding with portmap or whatever it's called
nowadays (rpc.portmapd? rpcbind?), you can feed mountd the -p flag, but you
might have to adjust the clients then, too.

Maybe. Kinda depends on what the default is and whether it's been changed
somewhere down the line. It's something to check. :-)
