- init: add condition_path_exists so optional-daemon units (dbus, seatd,
thermald, evdevd) are silently skipped when their binary is absent in a
minimal image, instead of emitting [FAILED] 'No such file or directory' on
the bare target. Boot-critical units omit the field and still hard-fail.
- ahcid: an empty ATAPI/optical drive (QEMU's default DVD-ROM, most bare-metal
optical bays) failed READ CAPACITY and logged 4 ERROR lines every boot;
register it with a zero block count as a normal no-media state and drop the
HBA register dump to debug level.
- netstack: a machine with no NIC (bare, or an unsupported NIC) logged an ERROR
and exited non-zero; treat 'no network adapter' as a normal idle state
(info + clean exit).
- dhcpd: cut the socket timeout 30s -> 8s so the network stage fails fast when
no DHCP server answers instead of stalling boot.
