I suspect I may be seeing a variant of this. Until yesterday I was still on Debian jessie, using systemd since I upgraded to that version, with no steps taken to limit systemd's authority over the system.
Yesterday I did an in-place upgrade to stretch, as it's now entered
freeze, and immediately encountered issues with mounts. One was an
unrelated issue with still having a line in /etc/fstab to mount
/proc/bus/usb which is no longer valid.
The other issue is that my two NFS mounts from my server (still on
jessie) were failing at boot-time. After I fixed the /proc/bus/usb
issue (by commenting that line out) the next boot had my NFS mounts work
OK. But today they've failed again.
The two lines in /etc/fstab are:
192.168.1.1:/home/users /home/users nfs
defaults,soft,intr,timeo=50,retrans=6,fg,nfsvers=3,nosuid,nodev,nofail 0 0
192.168.1.1:/mnt/tuesday/data0 /mnt/tuesday/data0 nfs
defaults,soft,intr,timeo=50,retrans=6,fg,nfsvers=3,nosuid,nodev,nofail 0 0
and these always worked 100% on jessie by the time I'd typed in my
password. In stretch, due to /home/users not being properly mounted I
could not complete a login.

I then switched to a text console, logged in as root, and ran 'systemctl
start home-users.mount' (and similar for mnt-tuesday-data0.mount) and
that worked without issues. So there's obviously some race
condition/lack of interlock with something else being finished starting.
If further information is required I'll capture it when it's in the
"failed to mount automatically during boot" state, before I mount
manually.
