AT&T AST and ARB (rDNA data cruncher) certainly have worked with Cygwin on NFS shares (Windows builtin, I think you call it MSFT NFSv3) in the past in our institute. Tested with Cygwin 3.4.8: AST is not even building without such support, and ARB throws nasty errors in the cluster run setup phase II, because it cannot create the command fifo used for each cluster node. > > Cygwin FIFOs are > created as symlinks of the type Windows shortcut with the R/O attribute > set. Those are only generated on NTFS and FAT filesystems. NFS symlinks > are generated using special magic. NFS doesn't support DOS attributes. So no Linux mkfifo support on NFS with Cygwin?
