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

junction path/to/cgi-bin path/to/htdocs/revealscript

is just one example, I'm not going to repeat 20 years of security issues
surrounding symlinks for your benefit.

Junctions are alias/symlinks.  A junction cannot point at an unmounted volume.

E.g. although my checkouts to develop apr on httpd look like


so that svn up httpd-* apr-* bring all sources up-to-date, 

                         apr <junction to apr-1.3>
                         apr-util <junction to apr-util-1.3>
                         apr-iconv <junction to apr-iconv-1.3>

Please don't tell me that this facility doesn't expose the same issues as
symlinks raise.  That's why APR was designed to handle symlinks in this manner.

The symlink protection is in there to help determine when aliases exist.

Precisely.  This is exactly the same impact on unix of a symlinked directory.  
Ergo the portability behavior is 100% correct, and this discussion really 
is finished.
