[Bug 1312976] Re: nfs-utils needs systemd unit or init.d script

[Martin Pitt]

Taking over from Steve as discussed on IRC, he doesn't find enough time
for this.

These are the steps to set up a VM to test both server and client:

# set up exports
sudo apt-get install -y nfs-kernel-server
echo -e '/home *(rw,no_subtree_check)\n/var/log/ *(ro,subtree_check)' | sudo tee -a /etc/exports
sudo service nfs-kernel-server start

# set up client mounts
sudo mkdir /mnt/nfs_home /mnt/nfs_log
cat << EOF | sudo tee -a /etc/fstab
localhost:/home /mnt/nfs_home nfs defaults,nofail 0 0
localhost:/var/log /mnt/nfs_log nfs defaults,nofail 0 0
EOF
sudo reboot

# some simple tests to see that it worked
ls -l /mnt/nfs_log/wtmp /mnt/nfs_home/ubuntu/.bash*
echo hello > /mnt/nfs_home/ubuntu/world.txt
cat ~/world.txt   # should give "hello"
sudo touch /mnt/nfs_log/pwned  # should fail with "read-only fs"

This works fine under upstart, but as expected fails once you install
systemd-sysv:

$ sudo systemctl status nfs-kernel-server
● nfs-kernel-server.service - LSB: Kernel NFS server support
   Loaded: loaded (/etc/init.d/nfs-kernel-server)

and the client mounts hang:

$ ps aux|grep nfs
