The "lrrd" service seems to be some historical cruft, that is no longer
in use. It is still an alias for the "munin" service (port 4949) in
/etc/services, but probably not in use anymore.
Packagers (e.g. for OpenWrt) usually pick a different path (e.g.
/usr/bin/muninlite or /usr/sbin/muninlite), but a native installation
from source should point to /usr/local/... by default.
The change affects only examples, thus it should do no harm.
Previously MuninLite tried to create a drop-in-replacement for
munin-node by using the same name. But MuninLite behaves differently
and may even be used in parallel to a regular munin-node setup on a host,
thus it should use a distinct name.
