# Systemd provides a binary for verifying the correctness of
# unit files. Unfortunately some units have constraints on the
# filename meaning that normal verification against temp files
# won't work.
#
# Working around that requires placing a copy of the temp file
# in a temp directory, under its real name and running the
# verification tool against that file.
