With some further testing, it would seem that the issue of not being able to find/access anything under that path with the intermediate symlink affects all services,not just nfs. I'm seeing it with git-daemon-run (which runs via runit), as well as with apache (the gitweb site is unable to follow those symlinks). I'm completely stymied at what the cause might be. Is systemd somehow passing a different view of mounted filesystems to its children?
