【资料目录和简介】：

Cygwin supports both POSIX- and Win32-style paths. Directory delimiters may be either forward slashes or backslashes. Paths
using backslashes or starting with a drive letter are always handled as Win32 paths. POSIX paths must only use forward slashes
as delimiter, otherwise they are treated as Win32 paths and file access might fail in surprising ways.
Note
The usage of Win32 paths, though possible, is deprecated, since it circumvents important internal path handling mechanisms.
See Section 3.1.6 and Section 3.1.7 for more information.
POSIX operating systems (such as Linux) do not have the concept of drive letters. Instead, all absolute paths begin with a slash
(instead of a drive letter such as "c:") and all file systems appear as subdirectories (for example, you might buy a new disk and
make it be the /disk2 directory).
Because many programs written to run on UNIX systems assume the existence of a single unified POSIX file system structure,
Cygwin maintains a special internal POSIX view of the Win32 file system that allows these programs to successfully run under
Windows. Cygwin uses this mapping to translate from POSIX to Win32 paths as necessary.
3.1.2 The Cygwin Mount Table
The /etc/fstab file is used to map Win32 drives and network shares into Cygwin’s internal POSIX directory tree. This is a
similar concept to the typical UNIX fstab file. The mount points stored in /etc/fstab are globally set for all users. Sometimes
there’s a requirement to have user specific mount points. The Cygwin DLL supports user specific fstab files. These are stored in
the directory /etc/fstab.d and the name of the file is the Cygwin username of the user, as it’s stored in the /etc/passwd
file. The structure of the user specific file is identical to the system-wide fstab file.
