Allocate system users and groups
systemd-sysusers [OPTIONS...] [CONFIGFILE...]
systemd-sysusers.service
systemd-sysusers creates system users and groups, based on the file format and location specified in sysusers.d(5).
If invoked with no arguments, it applies all directives from all files found. If one or more filenames are passed on the command line, only the directives in these files are applied. If only the basename of a file is specified, all directories as specified in sysusers.d(5) are searched for a matching file.
The following options are understood:
--root=root
Takes a directory path as an argument. All paths will be prefixed with the given alternate root path, including config search paths.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
On success, 0 is returned, a non-zero failure code otherwise.
