декларативное распределение пользователей и групп системы (Declarative allocation of system users and groups)
Описание (Description)
systemd-sysusers
uses the files from sysusers.d directory to
create system users and groups and to add users to groups, at
package installation or boot time. This tool may be used to
allocate system users and groups only, it is not useful for
creating non-system (i.e. regular, "human") users and groups, as
it accesses /etc/passwd and /etc/group directly, bypassing any
more complex user databases, for example any database involving
NIS or LDAP.
