This is controllable:
- eclean-dist cleans what is in the tree no longer and not
installed in the system;
- eclean-dist -d cleans everything not installed in the system.

One can also restrict cleaning by file date (e.g. don't touch files
newer than) or by file size; fetch-protected files may be spared
as well. See
  eclean-dist --help
for more details.

We have a cluster of identical machines. Exporting over NFS works
just fine, though we exported not only /usr/portage,
but /usr/local/portage, /var/lib/layman and /var/cache/edb/dep as
well (we use sqlite backed for portage).
