The problem is, it works fine on local and remote NTFS, as well as on Samba. Since the number of open handles doesn't depend on the underlying filesystem, why should it fail for NWFS? > Looking at the strace output of both rm-7.0 and rm-8.10 it seems > that rm-8.10 thinks that lev1 is a file, because it uses unlink_nt() > first. unlink_nt is used by unlink as well as by rmdir since the system calls to delete a file are the same as the calls to delete a directory. > 216 174576 [main] rm-8.10 336 unlink_nt: Opening file for delete > failed, status = 0xC0000043 > 240 174816 [main] rm-8.10 336 seterrno_from_nt_status: > /netrel/src/cygwin-snapshot-20111017-1/winsup/cygwin/fhandler_disk_file.cc:1735 > status 0xC0000043 -> windows error 32 That's a sharing violation. Where's the difference to the strace output with the exact same Cygwin DLL and rm from coreutils 7?
