       This manual page describes how to manage kresd using systemd units.

       QUICKSTARTsystemctlstartkresd@1 - single instance of kresd, responding on localhost

       CONCURRENTDAEMONSkresd  daemon  can  be  executed  in  multiple  independent processes, which are managed with systemd via
       systemd templates (see  systemd.unit(5)).   Each  systemd  service  instance  of  kresd  (kresd@.service)
       represents a single, independent kresd process.

       If you have more than one CPU core available, a single running kresd daemon will only be able to make use
       of  one  core  at  a  time,  leaving  the  other  cores idle.  If you want kresd to take advantage of all
       available cores, while sharing both cache and sockets, you should enable and start as many  instances  of
       the kresd@.service as you have cores.  Typically, each instance is just named kresd@N.service, where N is
       a decimal number. For example, to enable and start 3 concurrent daemons:

           systemctlenable--nowkresd@1.servicekresd@2.servicekresd@3.service

       The systemd-managed kresd service set is grouped in the system-kresd.slice slice.  The slice includes all
       running daemons (instances of kresd@.service).

       To start a single kresd instance and enable it at boot:
           systemctlenable--nowkresd@1.service

       To  restart  (or stop) all running instances, you can use a glob expression.  Please note that glob can't
       be used to start or enable instances.
           systemctlrestart'kresd@*'

       Bash users can also use Brace Expansion to enable or start multiple instances, instead  of  listing  them
       manually.
           systemctlenable--nowkresd@{1..4}.service

       To start all enabled kresd daemons, you can also use the provided kresd.target:
           systemctlstartkresd.target
