Comment 2 for bug 1709186

From log:

insserv: warning: script 'refdb' missing LSB tags and overrides
insserv: There is a loop between service reniced and refdb if stopped
insserv: loop involving service refdb at depth 2
insserv: loop involving service reniced at depth 1
insserv: Stopping refdb depends on reniced and therefore on system facility `$all' which can not be true!
insserv: exiting now without changing boot order!
update-rc.d: error: insserv rejected the script header
