Question: mountd not get started?

Hi, your repository saved my days. Thanks.

Background and problem

I have modified your Dockerfile a little bit like this

FROM alpine:latest

RUN apk add --no-cache nfs-utils

ADD https://github.com/just-containers/s6-overlay/releases/download/v1.21.2.1/s6-overlay-amd64.tar.gz /tmp/
RUN tar xzf /tmp/s6-overlay-amd64.tar.gz -C /

COPY s6/config.init /etc/cont-init.d/00-config
COPY s6/rpcbind.run /etc/services.d/rpcbind/run
COPY s6/mountd.run /etc/services.d/mountd/run

EXPOSE 111/udp 2049/tcp 2049/udp

# Added
RUN echo '/mnt *(rw,fsid=0,root_squash,no_subtree_check,insecure)' >> /etc/exports

CMD ["/init"]

build

docker build . -t otiai10/nfs-server

run

docker run \
  -it --rm --privileged \
  -p 111:111/udp -p 2049:2049/tcp -p 2049:2049/udp \
  -v /mnt:/mnt \
  otiai10/nfs-server

then I got

[s6-init] making user provided files available at /var/run/s6/etc...exited 0.

rpc.mountd: Version 2.1.1 starting

Seems working well half the way, but it stucks on rpc.mountd: Version 2.1.1 starting.

From client side,

[root@ip-172-31-30-27 ~]# mount -t nfs -o nfsvers=4,proto=tcp 172.31.29.92:/mnt foobar
mount.nfs: mounting 172.31.29.92:/mnt failed, reason given by server: No such file or directory
