stat() fails on /@unixroot

[dmik]

If you do

  struct stat st;
  int rc = stat("/@unixroot", &st);

you will get -1 and errno=2. OTOH, stat("/unixroot/")(i.e. with a trailing slash) works fine.

This is a bogus behavior since for all other directory paths the result will be the same, regardless of the trailing slash.

This in particular affects the Python's os.path.realpath implementation (together with another defect), see #284 for more details.

I guess that for the same (or a similar) reason this command

install -d /@unixroot/usr/local

fails with:

install: cannot create directory `/@unixroot': File exists

I guess you may be using UNIXROOT=X: instead of UNIXROOT=X:/. As of r3917 / r3918 that's accepted and corrected automatically (also correcting UNIXROOT=E:/myunix/// to UNIXROOT=E:/myunix automatically). This is possibly a problem with the re-writer rule validation, and/or assumptions in the fsResolveUnix() code about getting something with a root slash after rewriting.

I used UNIXROOT=x: in all rpm/yum installations... but it is good to know it is now officially supported :-))
