Both find and coreutils df use the gnulib module mountlist.c to build an internal cache of all mount points up front, rather than constantly querying if a particular directory is a mount point. Is it not possible for cygwin's implementation of getmntent() to also return junctions/reparse points as mount table entries, to give an accurate picture of all mount points to tools that need it? Mount points don't usually change during operation, so cygwin could take the same approach of caching all Windows mount points up front at the same time it caches cygwin mount points; isn't it possible for such caching to be done once as cygwin1.dll initializes and shared, rather than once per process that uses cygwin1.dll? Yes, I know, PTC. - -- Life is short - so eat dessert first!
