systemd-sysusers, systemd-sysusers.service - Allocate system users and groups
[OPTIONS...] [ CONFIGFILE...]
creates system users and groups, based on the file
format and location specified in sysusers.d
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. If the string "-" is specified instead of a filename, entries
from the standard input of the process are read.
The following options are understood:
Takes a directory path as an argument. All
paths will be prefixed with the given alternate root path, including
config search paths.
Print a short help text and exit.
Print a short version string and exit.
On success, 0 is returned, a non-zero failure code otherwise.
