Yes, I know that, but the question is how devd(8) parses the
action strings.
The problem here is that we have multiple levels or parsing.
First, devd reads the line, concatenates continuation lines
(apparently -- it's not documented), expands devd variables,
and *then* it passes the resulting string to the shell for
further parsing and processing.
Best regards
