-# systemd doesn't know to do path escaping on the instance variable we pass
-# to the e2scrub service, which breaks things if there is a dash in the path
-# name. Therefore, do the path escaping ourselves if needed.
-#
-# systemd path escaping also drops the initial slash so we add that back in so
-# that log messages from the service units preserve the full path and users can
-# look up log messages using full paths. However, for "/" the escaping rules
-# do /not/ drop the initial slash, so we have to special-case that here.
