Device handling is implemented via plug-in programs known as policy methods. Policy methods are free to handle their devices in any way, from trivial to complex - anything from providing LSB device nodes to persistent device name handling with replacement and relocation strategies. The uSDE depends on /sbin/hotplug (for dynamic insertions and removals), sysfs (for device information) and /proc (various pieces of information). It is not dependent on initrd - it explicitly scans sysfs upon system startup to determine the initial device ensemble. Part of the uSDE release is a collection of sample polices: disk-ide-policy - handles IDE, EIDE, SATA and USB-EIDE disks. Implements persistent device naming, automatic device replacement and automatic device relocation features. disk-scsi-policy - handles SCSI, IEEE-1394, FibreChannel and USB-SCSI disks including multiported devices. Iplements persistent device naming, automatic device replacement and automatic device relocation features. multipath-policy - handles the automatic provisioning of multipathing for multiported storage devices. ethernet-policy - handles ethernet interefaces. Implements persistent interface naming, interface anchoring, automatic device replacement and automatic device relocation features. floppy-policy - handles internal floppy disks. simple-device-policy - a "catch all" policy for block and character devices. devfs-policy - provides devfs device names. lsb-policy - provides LSB device names.
