it walks each element of the union, dns is at the back,
and it puts dns: in front of its Rerror replies.

/mnt/foo's diagnostic is (in a similar way) factotum

/srv is devsrv.c's (and the kernel's Enoent)

directory entry not found is the file server

it'll also help with internationalization, if that ever becomes a
desired feature.

it'd be nice if there was a standard diagnostic that programs could
test against if they wished.

it shouldn't take much effort to just go through the various
instances, standardising the "file does not exist" message...

i like the 'ascii text style', but what a nightmare when it comes to
internationalisation.
