just use rsyslog a all the years before

rsyslog.conf:
$MainMsgQueueSize 100000
$WorkDirectory /var/lib/rsyslog
module(load="imjournal" StateFile="imjournal.state"
WorkAroundJournalBug="on")
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$MaxMessageSize 4096
:programname, isequal, "dhcpd" -/var/log/dhcpd.log
:programname, isequal, "dhcpd" stop

what exactly did you not understand in my repsonse that you need to use
rsyslog for traditional logfiles and why do you respond to your own post
instead already existing answers?

Some daemons provide an option to log to file, use that if available,
otherwise make your program write debug or log messages to stderr and
the journal will capture it.. then you can extract them to a text file.
