|I don't know anything about vnodes, but I've puzzled over that cryptic
|errmessage from mount before. It's telling you that you don't have a
|proper file system. You need the msdos equivalent of newfs ("format" in
|DOSspeak?) before the mount command.
Well, actually doscmd_C_drive is a valid FAT file system. In fact, I dd'ed
it off a real disk into a file, and doscmd runs happily with it.
Question is, can the vnode system handle MSDOS/FAT?
For now, I just copy the files inside doscmd from the DOS prompt by
pointing its D: to a UFS disk:
assign hard /wd4tmp/doscmd/doscmd_C_drive 65 255 63
assign D: -ro /c
but it would be useful to be able to copy files into/out of the doscmd file
system (doscmd_C_drive file) w/o firing up doscmd.
