Systemd explicitly calls its function
extract_first_wordwith the attributeEXTRACT_UNQUOTE, hence the string handed over perENV{SYSTEMD_*WANTS}=""from udev to Systemd (and then the separated instance string to the called unit) can be hard-quoted (per "'"), becomes unquoted by Systemd (then still including the unit name) and should ultimately arrive at the called unit (the instance string as "%i") as it was originally inserted intoPROGRAM="".In somebody else's words.
