I mount a network drive over nfs at boot that contains the built IOC binaries for the service to run. The service is enabled, it should start at boot but it doesn’t because the ConditionPathIsDirectory fails. If I go to the directory after the system has booted, I can see that it has been mounted correctly and exists. I cc Wayne because I seem to remember us having a similar problem at ESS about 2 years ago but I can’t remember how we solved it! Does anybody have any ideas?

How is the relevant NFS share being mounted?  Via /etc/fstab, autofs,
or some other initiator?

I think that "After=network.target remote-fs.target" should be enough
to ensure ordering.  You could try adding
"Requires=network.target remote-fs.target".
