Yes, I followed that part; I'm doing something similar, e.g. /usr/src/
on my build host has 3 symlinks to automounted NFS dirs today for

  current
  netbsd-10
  netbsd-11

with obj/, tools/, and xsrc/ setup similarly. I'll likely append the
arch name to the obj/<src version>/ path name, as you suggested.

The other (amd64) buildhost doesn't share dirs with the rpi4 buildhost
except (x)src/, as it has its own obj/ and tools/ dirs.

Thanks again,
