       nss-systemd, - Provide UNIX user and group name resolution for
       user/group lookup via Varlink



       nss-systemd is a plug-in module for the GNU Name Service Switch (NSS) functionality of the
       GNU C Library (glibc), providing UNIX user and group name resolution for services
       implementing the User/Group Record Lookup API via Varlink[1], such as the system and
       service manager systemd(1) (for its DynamicUser= feature, see systemd.exec(5) for details)
       or systemd-homed.service(8).

       This module also ensures that the root and nobody users and groups (i.e. the users/groups
       with the UIDs/GIDs 0 and 65534) remain resolvable at all times, even if they aren't listed
       in /etc/passwd or /etc/group, or if these files are missing.

       This module preferably utilizes systemd-userdbd.service(8) for resolving users and groups,
       but also works without the service running.

       To activate the NSS module, add "systemd" to the lines starting with "passwd:" and
       "group:" in /etc/nsswitch.conf.

       It is recommended to place "systemd" after the "files" or "compat" entry of the
       /etc/nsswitch.conf lines so that /etc/passwd and /etc/group based mappings take


       Here is an example /etc/nsswitch.conf file that enables nss-systemd correctly:

           passwd:         compat mymachines systemd
           group:          compat [SUCCESS=merge] mymachines [SUCCESS=merge] systemd
           shadow:         compat

           hosts:          files mymachines resolve [!UNAVAIL=return] dns myhostname
           networks:       files

           protocols:      db files
           services:       db files
           ethers:         db files
           rpc:            db files

           netgroup:       nis
