Many thanks Steffen and Merlin for your configuration details!
I learned a lot already and I believe that we are on the right track.
I included your suggestions into my dhpcd.conf .
According to the log output below it seems to select the correct file now.
But I still could not yet get it to work correctly.
In order to debug this I increased the tftpd verbosity level. And this is what
I now get in daemon.log when I try again:

10.250.217.16 is the installation client.
Any idea which read failed for tftpd ?
The syslinux files all are mode 644, so they are readable. Directories are 755.
What may refuse the connection for tftpd?
have you considered tcp wrappers ?
ldd $(which in.tftpd) | grep wrap
libwrap.so.0 => /lib/x86_64-linux-gnu/libwrap.so.0 (0x00007f9b39f41000)
perhaps this will solve the issue...
echo in.tftpd: ALL >> /etc/hosts.allow
change ALL for something more restrictive perhaps.
