Subject DO NOT REPLY [Bug 47630] NTFS directory junctions ("mounted folders") should be treated like n*x mount points (APR_DIR, not APR_LNK)

I am studying that relationship to determine how we will finally implement
apr_file_symlink_create() et al.  Most likely, in XP/2003 directory symlinks
will continue to be junctions, while Vista/2008 with upgraded NTFS file systems
would gain symlinks.  The 1/2 hour of testing I did today was not promising.

But Junctions have no relationship to unix mount points.  Just like symlinks,
junctions and mount points can be renamed.  Unlike mount points, the change
is immediate.  It is not at the driver layer.  In the unix case, the mount
is at a much lower level, and that rename causes the system to fail (in fact,
it isn't possible).

You are missing the distinction between kernel layer/driver driven mounts, such
as unix and also windows drivers, and userspace controllable filesystem
aliases.
A Junction is a symlink-style alias, and for security must be represented as
such, because any user can manipulate them.  End of discussion.

Ok, this is clearly confusion on your point as to the flexibility of Junctions
and where they sit on the driver stack.  Meaning no disrespect, I am closing
this bug as invalid.
