With the standard /net -hosts definition, automounting NFS doesn't work. The very same works with F15. Exists in F16 TC2 (and probably earlier) both with and without latest from updates-testing. If you try ls /net/your-nfsserver.localdomain/ it will create all available exports. If you try to enter one specific mount point, that will fail and the log says that's because 'file exists'.

This is because systemd marks the root file system shared which causes any move mount system calls against any file systems to fail. Not really sure what to do about it and I'm not sure this is a sensible thing for systemd to do either. I guess that if you don't use the sandbox facility (at least I think that's what it's called) you could probably mark the root filesystem as private as a workaround.
So, is there any plan to fix this? Is it an autofs or systemd issue, i.e. should I change the component this bug is reported against? Or shall we add systemd's maintainer to the CC list and ask for advice? Also, how do you mark filesystems shared/private?
