# The file fstab contains descriptive information about the various file
# systems. fstab is only read by programs, and not written; it is the
# duty of the system administrator to properly create and maintain this
# file. Each filesystem is described on a separate line; fields on each
# line are separated by tabs or spaces. Lines starting with '#' are com-
# ments.
#
# The first field, (fs_spec), describes the block special device or
# remote filesystem to be mounted. On Cygwin, this is the native Windows
# path which the mount point links in. As path separator you MUST use a
# slash. Usage of a backslash might lead to unexpected results. UNC
# paths (using slashes, not backslashes) are allowed. If the path
# contains spaces these can be escaped as '\040'.
#
# The second field, (fs_file), describes the mount point for the filesys-
# tem. If the name of the mount point contains spaces these can be
# escaped as '\040'.
#
# The third field, (fs_vfstype), describes the type of the filesystem.
# Cygwin supports any string here, since the file system type is usually
# not evaluated. The noticable exception is the file system type
# cygdrive. This type is used to set the cygdrive prefix. See the
# user's guide for more information about the cygdrive prefix.
#
# The fourth field, (fs_mntops), describes the mount options associated
# with the filesystem. It is formatted as a comma separated list of
# options. It contains at least the type of mount (binary or text) plus
# any additional options appropriate to the filesystem type. Recognized
# options are binary, text, nouser, user, exec, notexec, cygexec, nosuid,
# managed. For a description of the options see the user's guide. Note
# that nouser mount points are not overridable by a later call to
# mount(2). This is only possible for user mount points. Mount points
# are by default nouser mount points, unless you specify the option user.
#
# The fifth (fs_freq) and sixth (fs_passno) field are ignored. They are
# so far only specified to keep a Linux-like fstab file layout.
#
# Note that you don't have to specify an fstab entry for the root dir,
# unless you want to have the root dir pointing to somewhere entirely
# different (hopefully you know what you're doing), or if you want to
# mount the root dir with special options (for instance, as text mount).
#
# Example entries:
#
# Just a normal mount point:
#
# c:/foo /bar fat32 binary 0 0
#
# A mount point for a managed, textmode mount:
#
# C:/foo /bar/baz ntfs text,managed 0 0
#
# A mount point for a Windows directory with spaces in it:
#
# C:/Documents\040and\040Settings /docs ext3 binary 0 0
#
# A mount point for a remote directory:
#
# //server/share/subdir /srv/subdir smbfs binary 0 0
#
# This is just a comment:
#
# # This is just a comment
#
# Set the cygdrive prefix to /mnt:
#
# none /mnt cygdrive binary 0 0
