# 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, system, user, exec, notexec, cygexec, nosuid,
|
||||
# managed. For a description of the options see the user's guide. Note
|
||||
# that system 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 system 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
