Hi-
There IS a document for GNU tar that was provided with - oh ,
gee, I think 1.10. It is now somewhat out of date. Anyway, I
believe that if you want to tar out to multi-volume floppies
you want to do something like this
tar cvMbf 15 /dev/fd0 .
The block size should be the number of sectors in a track on
your floppy (that is, 15 for 5.25", 18 for 3.5".) Otherwise
the write fails in the middle of a block and all hell breaks
loose. I haven't actually TRIED this on Linux, but I do
read floppies on Linux all the time that were made this way
on a Sun.
Also, you can't use the -Z compression option along with the
-M multi-volume option. Please also note that case is important
with the options.
