Please forgive my confusion, but that's what I did, didn't I? I create
the package at installation time in maintainer script if it is missing
and never again. I don't touch or modify the init script at all.
Aside I agree with you. I understand it as a state file as well, which
must be persistent across reboots, but not be modified at start time or
anytime again.
So we may discuss whether we need some contents to initialize it for the
first time the package is installed. Note, our own man pages previously
suggested to do this:
"before starting the server for the first time, create an empty
/var/db/nfs-stablerestart
file. The command
install -o root -g wheel -m 600 /dev/null /var/db/nfs-stablerestart
executed as ``su'' should suffice. This can only be done when the
server is not running and there are no nfsv4 file system mounts against
the server. If this file is lost during a crash, recovery from backups
is recommended." [1]
The 9.0 version of nfsv4.4 lacks this part, however.

It works for me, YMMV.
