MS-DOS filesystems under SunOS 4.x

[Steve M. Burinsky]

I know that someone has gone to the trouble of writing MTOOLS, a package
for reading/writing MS-DOS filesystems to the 3.5 inch floppy drive on
SPARCstations.  Recently, I was poking around the kernel source code and
learned that all the code for MS-DOS file systems is apparently in place,
just waiting for someone to turn on the PCFS option and rebuild the
kernel.  (Actually, mount(8) would also have to be rebuilt.)

Have I been missing something?  I don't ever remember hearing about MS-DOS
filesystem support before.  How come it isn't mentioned in the
documentation?  The mount(8) man page doesn't say a word about it.  

Before I go to the trouble of trying this, I'd like to know if it's
already been done.
