Role subpackages set the system-wide default qdisc and TCP congestion control via /usr/lib/sysctl.d, without pulling in the base package: server fq + bbr bare metal, VM guests vmhost fq_codel + bbr hypervisors, container hosts router fq_codel + cubic desktop fq_codel + cubic The base package applies cake per interface from /etc/qos-profiles/<iface>.conf, layered over role defaults and /etc/qos-profiles/defaults.conf: - LINK_RATE with per-direction overrides, shaped to SHAPE_PERCENT (default 95, per direction overridable) - outbound fairness per source host and diffserv4; inbound via ifb, fairness per destination host, besteffort with DSCP wash - NAT awareness, extra cake args (shared and per direction), raw qdisc overrides - config parsed without executing it, validated before any change, previous state undone on each run Applied by the qos-profiles@<iface> unit (bound to the device) or the qos-profiles-networkmanager dispatcher subpackage, installed automatically on hosts with NetworkManager. Includes ready-made examples for VM hosts, OVH dual-NIC servers, DC and home routers.
