K 10 svn:author V 6 mjacob K 8 svn:date V 27 1998-12-17T18:56:23.000000Z K 7 svn:log V 486 Several changes having to do blocksize- mostly to force variable as the default. Attempt to determine (at mount time if not done so already) via density code whether a device should default to fixed mode or not. Attempts to set to variable that fail will cause fixed to be selected. Similarly, the '2 filemarks at EOM' quirk is now determined (or attempted to be determined) via density code. Some as yet not entirely tested code for coping with 2FM@EOD position is now also in place. END
