221519d15cSJohn Baldwin# Large block comments should begin and end with a line containing only a
231519d15cSJohn Baldwin# comment character.
241519d15cSJohn Baldwin#
251519d15cSJohn Baldwin# To describe a particular object, a block comment (if it exists) should
261519d15cSJohn Baldwin# come first.  Next should come device, options, and hints lines in that
271519d15cSJohn Baldwin# order.  All device and option lines must be described by a comment that
281519d15cSJohn Baldwin# doesn't just expand the device or option name.  Use only a concise
291519d15cSJohn Baldwin# comment on the same line if possible.  Very detailed descriptions of
301519d15cSJohn Baldwin# devices and subsystems belong in manpages.
311519d15cSJohn Baldwin#
321519d15cSJohn Baldwin# A space followed by a tab separates 'option' from an option name.  Two
331519d15cSJohn Baldwin# spaces followed by a tab separate 'device' from a device name.  Comments
341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.
351519d15cSJohn Baldwin# To comment out a negative option that disables code and thus should not be
361519d15cSJohn Baldwin# enabled for LINT builds, precede 'option' with "#!".

802ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
803ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
804ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
805ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
806ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
807ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
