Public bug reported:

Autofs remounts NFS filesystems after the timeout is up. For example, if autofs.master contains:
/net    -hosts noexec --timeout=30
If I then access /net/host/path/somewhere autofs will mount correctly and I can then see that the systemd unit net-host-path-somehwere.mount is visible and shows as active. If I then close anything open on that share I can see that after about 30s systemctl will start reporting:
Unit net-host-path-somehwere.mount could not be found
as I expect. However, within a few seconds systemctl will start again reporting that the unit is active and mounted. This then repeats; despite the fact I am not trying to access the mount. This means that the remote nfs file system never really unmounts despite the fact it is not being used.
