FSTAB doesn't map a network connection when Network uses fixed IP address only.

[CanberraPete]

I noticed that on both a Pi4 and Pi5 (with a fixed IP address assigned to he interface) that attempting to mount a network share to /PVR doesn't work at boot.
DMESG says the network wasn't ready.
Once booted, If I do a "sudo mount -a" form the terminal the connection works/mounts.

However if I configure the network interface (ethernet) to DHCP it connects at boot every time.

My work around has been to leave DHCP enabled but add a secondary IP address to the interface.
( I could reserve the IP in the scope but that would mean changing the range and I didn't want that.. A fixed IP should work).

Thanks.

Does the "Network at boot" option in raspi-config help? https://www.raspberrypi.com/documentation/computers/configuration.html#menu-options

In general, whenever the topic of static IP addresses comes up, the general recommendation is to leave the Pi set to DHCP, and create a static mapping for the Pi's MAC address in your router's settings.

That option was removed in Raspberry Pi OS Bookworm, so unless the OP is using an old version of the OS it won't be present on their system.

(The reason it was included in previous versions was to workaround the fact that dhcpcd does not support the required systemd targets, e.g. network-online.target. The Bookworm-based version of Raspberry Pi OS uses Network Manager instead of dhcpcd).
