Package: systemd
Version: 215-17+deb8u4
In a scenario where the NFS server is not yet up when mounting an NFS
share at boot, the systemd *.mount unit times out and gets stuck in a
somewhat odd "active (mounted)" state, even though it is not actually
mounted. This appears to prevent any systemd *.automount unit from being
able to later mount it when the NFS server does come back online.
This means that in our scenario where the NFS server machine is slower
to boot up than the NFS client machines, we must perform manual
intervention on each of the client machines to mount the missing NFS
shares after e.g. a site-wide power failure. I had hoped that using
systemd.automount would handle this scenario better, having processes
attempting to use the NFS mount wait or return IO errors until the NFS
server eventually comes online and gets mounted.

I am reporting this as a bug since it appears that manually *stopping*
the *.mount unit to place it into an inactive state is enough to allow
the automounter to successfully mount it.
