ps *insists* on accessing floppy on Microport SysV/AT 2.4

Ahhh... for whatever reason (you pick one), the last informative posting
should have included more than my signature.  Let's try again...

I DON'T want to add to the confusion here, BUT, did things change that much
between SV/AT 2.3 and 2.4??  The directory in Steve's original posting is:

   brw-r--r--   1 root     sys        1,198 Mar 23  1986 /dev/swap
   brw-r--r--   5 root     sys        1, 70 Mar 28 17:21 /dev/dsk/fd
   brw-r--r--   1 root     sys        1,198 Mar 23  1986 /dev/dsk/0s25

On my SV/AT 2.3 system, /dev/dsk/0s25 is at major 6, minor 198, while
all partitions on the hard disk are at major device 4.  It certainly
looks to me like /dev/swap is on the floppy disk in Steve's system,
just as Piercarlo suspected.  /dev/swap lives at 4,1 on my system.

>>"ln /dev/swap /dev/dsk/fd" ??
>No you don't want to link it back to the floppy.

True enough, but it just looks to me like it's a duplicate entry instead
of a link.  Have I missed something obvious and just made an ass of myself?
Were the floppy and hard disk drivers coalesced in 2.4?  I don't see any
reason why they should be (or even why anyone would want to), but I'd be
interested to hear about it if they were.

John?
