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 +# +# 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 +# + +${CYGROOT//\\//}/bin /usr/bin ${FS_TYPE} binary,system 0 0 +${CYGROOT//\\//}/lib /usr/lib ${FS_TYPE} binary,system 0 0 +# This is default anyway: +# none /cygdrive cygdrive binary,user 0 0 +EOF + ) +fi + +# Check for ${DEVDIR} directory + +if [ -e "${DEVDIR}" -a ! -d "${DEVDIR}" ] +then + # No mercy.
