[SCALE] nfs service not startable. (/etc/exports not being generated at least)

as commented in NAS-114501, the latest versions of scale no longer include functional nfs services :/

root@pine:~# cat /etc/version
22.02-MASTER-20220207-092926

the nfs-server service won't start, as /etc/exports doesn't exist.

root@pine:~# systemctl status nfs-server

3 directories, 5 files

there are a bunch of ancilary things that seem unfunctional, but I'm trying to avoid the red herring breadcrumb trail.
