Ok I've looked at it quickly.. here's how you do it.. 1/ the 'auto' feature does NOT work so use a floppy definition to start with.. vnconfig /dev/rvn0 /tmp/imagefile disklabel -w -r /dev/rvn0 floppy3 disklabel -r -e /dev/rvn0 [edit disklabel to taste.. make 'c' the whole file but make another partition to mount. 'c' is special. it will not show up in /dev.] newfs /dev/vn0a # not rvn0a, this is a bug. I will fix this. This has shown up a few bugs, not the least of which is that newfs opens the disk READONLY and is surprised when it is not allowed to write. [BUG] disklabel auto does something that stops it working when it can't read a disklabel from the device first. I think it tries to do one of those disklabel IOCTLs (which of couse fails) and bombs out. It also will not write a disklabel, even with -r, when it gets an error from some specific IOCTLs (which it should ignore) I will look at these problems when I get a chance. julian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
