I’m moving my backend to arm.
This works on x86_64 but …

[sandypit] /home/jam [451]% systemctl status dev-dvb-adapter0-frontend0.device
? dev-dvb-adapter0-frontend0.device - /dev/dvb/adapter0/frontend0
Loaded: loaded
Active: inactive (dead)

Mar 04 21:40:22 sandypit.home systemd[1]: dev-dvb-adapter0-frontend0.device: Job dev-dvb-adapter0-frontend0.device/start timed out.
Mar 04 21:40:22 sandypit.home systemd[1]: Timed out waiting for device /dev/dvb/adapter0/frontend0.
Mar 04 21:40:22 sandypit.home systemd[1]: dev-dvb-adapter0-frontend0.device: Job dev-dvb-adapter0-frontend0.device/start failed with result 'timeo>
Mar 04 21:50:43 sandypit.home systemd[1]: dev-dvb-adapter0-frontend0.device: Job dev-dvb-adapter0-frontend0.device/start timed out.
Mar 04 21:50:43 sandypit.home systemd[1]: Timed out waiting for device /dev/dvb/adapter0/frontend0.
Mar 04 21:50:43 sandypit.home systemd[1]: dev-dvb-adapter0-frontend0.device: Job dev-dvb-adapter0-frontend0.device/start failed with result ‘timeo>

[sandypit] /home/jam [452]% ls /dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/frontend0

Am I being silly, or is this a bug in systemd

It only works in systemd when you have added the udev rules that make
the devices visible to systemd. From Ubuntu:

root@mypvr:/etc/udev/rules.d# cat 99-tuner.rules
#
# Create systemd device units for capture devices
#
SUBSYSTEM=="video4linux", TAG+="systemd"
SUBSYSTEM=="dvb", TAG+="systemd"
SUBSYSTEM=="firewire", TAG+="systemd"
