There are some poor assumptions about telling people to use 'fdisk /mbr'.

First, not everyone has DOS.  Some of us have OS/2, or some version of
System V/386.  I'm certainly not going to buy a copy of DOS just so I 
can 'fdisk /mbr', and I know on one would actually suggest that anyone 
make a bootleg copy.

Second, not everyone that has DOS has DOS 5.  DOS 5 is the first version
that has the /mbr option.  See the above.

Third, and I've said this before, and yes, I've heard that the *real* 0.2
is supposed to address this, and yes, I know that there's a better version 
of bootblocks on agate; never the less, 386BSD shouldn't be messing with 
the master boot record.  Other UNIX implementations achieve what the 386BSD 
bootblocks do with a "boot partition", i.e. the vanilla master boot record 
boots a small executive in a "boot partition", which in turn boots UNIX.

There's a de facto, if not published, standard.  It should be followed.  
Anyone want to make a change to TCP/IP?  Or X?  Aw, come on, they're only 
little changes!  And they'll be so much better for the change!  No?  I 
didn't think so.
