Not beautiful, indeed.
I was playing around with this, and although that change would work
around the problem in (at least) most cases, I am not sure that it is
I am not an expert at filesystems, and certainly have little knowledge
of NTFS. However, my observations confuse me considerably. The main
issue is that if you read from a file (on NTFS, with a link count of
zero according to ls(1)), the link count becomes populated. I cannot
see how that would happen, because the ntnode structure link count is
not modified except when reading the whole structure from the disk,
and the on-disk node is not being changed. To confuse things further,
the link count is changed to 2, not 1, on ordinary files that have
only a single directory entry. I do not believe that streams are at
issue, because the file has no open file descriptors remaining
according to fstat(1).
Any thoughts from the experts?
Might Darwin have any useful hints?
