Yes, %H is substituted by systemd.

We would prefer not to hard-code policy like the output metric names
unnecessarily, given that the pcp2graphite invoker has apprx. the
right information already:

  pcp2graphite -m pcp.`hostname`. [...]

Though if pcp2graphite is being run against a remote -h HOST target,
then its hostname is what's probably desired. pcp appears to lack a
shell-friendly general one-shot value-fetcher to do the equivalent of
the above, but this might work well enough:

  pcp2graphite -h FOO -m pcp.`/usr/libexec/pcp/bin/pmhostname FOO`. [...]

(The latter works based on DNS, which is not the same thing as the
remote pmcd.hostname.)
