One of my managers told me that since you could make both ECKD (FICON)

done - z/Linux cannot read z/OS data and vice-versa.
Is this correct?
If so, what would it take to make z/Linux able to read z/OS data
directly? New drivers? A new file system? How hard would this be to
write?
A new file system device driver, or plug-in for FUSE. I don't know
how hard it would be. I remember someone a few years ago had written
such a thing to read, uh, some kind of MVS files. (I can't even spell
MVS, so don't look to me for help) ISAM? VSAM? Don't remember. I
think he was trying to find a buyer, don't know if he ever succeeded,
and I don't remember his name, but it wasn't one of the regulars on
the Linux/390 list.
I suspect it's pretty hard.
