Debian 10 box will not mount NFS share from /etc/fstab however executing mount -a mounts said share. I noticed a longer boot time.

Here are fstab entries I've tried:
192.168.1.115:/volume1/user/Pictures/NOAA-images/ /home/user/weather/images nfs
ac,user,nfsvers=3,x-systemd.requires=network-online.target,x-systemd.device-timeout=100
0 0
192.168.1.115:/volume1/user/Pictures/NOAA-images/ /home/user/weather/images nfs ac,user,nfsvers=3,_netdev 0 0
Also tried, with no success:
systemctl reenable home-user-weather-images.mount
systemctl daemon-reload
Here's what the fstab entry's service looks like when using the x-systemd options:

I would suggest two actions :
1- Adding the following to the mount options to delay the mount for some moment :
[Mount]
Options=late,nofail,x-systemd.automount,x-systemd.requires=network-online.target,x-systemd.device-timeout=10 0 0
2- In the section Install add the above so the nfs mount should be mounted before reaching remote-fs target.
[Install] WantedBy=remote-fs.target
Sometimes it could be due to DNS resolution, but i am not seeing it here.
EDIT : Since you have an embedded eno0 interface you must declare it on the DHCP configuration with it's correct name reason why you had cannot find eth0 device and sometimes Enabling / Disabling NetworkManager can cause NIC naming confusion.
The file /etc/network/interfaces.d/setup needs to be edited to reflect the proper device from eth0 to eno1.
networking.service also failed (yet somehow networking manages to work). My /etc/default/networking and /etc/dhcp/* files are unmodified. Here is the output from journalctl -u networking.service:

However my ethernet device is eno1:
$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether 54:b2:03:8d:53:f6 brd ff:ff:ff:ff:ff:ff
Checking dmesg again...
# dmesg | grep -i eth
[ 3.170430] e1000e 0000:00:1f.6 eth0: (PCI Express:2.5GT/s:Width x1) 54:b2:03:8d:53:f6

[ 3.171438] e1000e 0000:00:1f.6 eno1: renamed from eth0
Back to Google, looked up why ifup can't find renamed interface. Came across this answer. Checking my /etc/network/interfaces.d/setup:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
... looks like the smoking gun. I never edited this file; this is a week-old install so I don't know why this problem manifested. Edited that, reverted fstab to the non x-systemd entries and a reboot. Now it works.
Before I consider answering my own question it'd be interesting if anyone can explain why this mess happened in the first place then that could be the 'best answer.'
