44# DEBUG happens to be magic.
45# The following is equivalent to 'config -g KERNELNAME' and creates

334# The `gif' pseudo-device implements IPv6 over IP4 tunneling,
335# IPv4 over IPv6 tunneling, IPv4 over IPv4 tunneling and

338# GRE and MOBILE, as specified in the RFC1701 and RFC2004.
339# The `faith' pseudo-device captures packets sent to it and diverts them
340# to the IPv4/IPv6 translation daemon.

640# SCSI DEVICES
641
642# SCSI DEVICE CONFIGURATION
643
644# The SCSI subsystem consists of the `base' SCSI code, a number of
645# high-level SCSI device `type' drivers, and the low-level host-adapter
646# device drivers. The host adapters are listed in the ISA and PCI
647# device configuration sections below.
648#
649# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
650# that a given bus, target, and LUN always come on line as the same
651# device unit. In earlier versions the unit numbers were assigned
652# in the order that the devices were probed on the SCSI bus. This
653# means that if you removed a disk drive, you may have had to rewrite
654# your /etc/fstab file, and also that you had to be careful when adding
655# a new disk as it may have been probed earlier and moved your device
656# configuration around.
657
658# This old behavior is maintained as the default behavior. The unit
659# assignment begins with the first non-wired down unit for a device
660# type. For example, if you wire a disk as "da3" then the first
661# non-wired disk will be assigned da4.
662
663# The syntax for wiring down devices is:
664
665# device scbus0 at ahc0 # Single bus device
666# device scbus1 at ahc1 bus 0 # Single bus device
667# device scbus3 at ahc2 bus 0 # Twin bus device
668# device scbus2 at ahc2 bus 1 # Twin bus device
669# device da0 at scbus0 target 0 unit 0
670# device da1 at scbus3 target 1
671# device da2 at scbus2 target 3
672# device sa1 at scbus1 target 6
673# device cd
674
675# "units" (SCSI logical unit number) that are not specified are
676# treated as if specified as LUN 0.
677
678# All SCSI devices allocate as many units as are required.
