CD as floppy

[Zoran Kolic]

   Dear List!
   Some 6 months ago here
was a thread describing
the use of cd-rw in the
same manner as floppy. Then
I wasn't aware of possibility
to update small files on
daily basis. Now, I cannot
guess keywords to find it.
Content should be like: "take
cd-rw... disklabel/bsdlabel...
newfs /dev/cd0... mount...
copy this to there..."
   I wonder, does it work
with every cd-writer? (Ide,
Sony CRX225E QYB2, atapicam
scsi emulation.) Should I
install something more to
make it work? And, what is
a mechanism under the hood?
   Best regards
