Last time I tried it, I got an error from mkisofs complaining about the
file being bigger than 2GB.  Has growisofs changed to not use mkisofs?
My research into the ISO filesystem showed that the filesize is a 32 bit
field in the filesystem data structures.  Has the system been revisioned
to now work?

Never tried that.  But I routinely keep large ISO images on my hard
drives.  Never tried burning an non-iso fs to a CD/DVD.
