The fact that your owner is mkgroup-l-d is probably a hint - my guess is that cygwin is returning -1 because you haven't set up your user database correctly, rather than an actual device number. If that's the case, then cygwin could probably be fixed (device major/minor node numbers need not depend on whether the user database is set up correctly). At any rate, Cygwin does not necessarily use the same major/minor node numbers as Linux. Any use of mknod outside of creating named pipes is _highly_ platform dependent, and your best bet is to read the source code for the actual node numbers that cygwin supports rather than relying on something that worked for Linux. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
