djbdns-conf 1:1.05-15ubuntu2 (s390x binary) in ubuntu mantic

 For each kind of server (tinydns, dnscache, axfrdns, walldns, rbldns)
 upstream provides program to create service directory for that server.
 .
 Service directories are part of corresponding binary packages, the only
 case when you may need this package is unlikely case when you want to run
 several instances of same service at single machine.
 .
 Service directories, created by programs in this package are
 compatible with both runit(8) and daemontools(8) supervision suites,
 but are somewhat simplistic -- they store log files in same place as
 configuration, for example.
