说明
systemctl add-requires appends `Requires=` dependencies to a specified systemd target for one or more units. A `Requires=` relationship establishes a hard dependency: if any of the listed units fail to start, the target itself will also fail to activate. This command provides a programmatic way to establish unit dependencies without manually editing unit files or creating symlinks in `.requires/` directories.
