I am confused a bit. Although I can see (hardly though) the point but
I am not sure, yet another condition in unit files is required. IMHO
systemd can check if files required by a service exist (and some other
tests which more or less cover test(1) functions) and not lauch the
service if they does not but, it is up to the service to check the
files' contents. No matter if it is a single character or a 24Mpix jpeg
file.
Technically, except for the notes already given by others, the patch
does not look bad.
