command. Changes made to a WIM mounted read-write will be discarded unless the
\fB--commit\fR flag is provided to \fBwimlib-imagex unmount\fR.
.SH DATA AND METADATA SUPPORT
-This section documents which WIM features are exposed via the mount support and
-which are not.
-.PP
-The following features are \fIsupported\fR (read/write unless otherwise
-specified):
+WIM images can contain a variety of types of files and file metadata, some of
+which is Windows-specific. Currently, the mount feature can translate some, but
+not all, Windows concepts to Linux equivalents. Briefly, the following features
+are \fIsupported\fR (read/write):
.IP \[bu] 4
Hard links
.IP \[bu]
automatically be translated into native Windows symbolic links.
.IP \[bu]
Named data streams (mostly). See the \fB--streams-interface\fR option.
-.IP \[bu]
-Standard UNIX permission bits and UNIX special files are supported if the
-\fB--unix-data\fR option is used.
.PP
-The following features are \fIunsupported\fR:
+In addition, standard UNIX file permissions (owner, group, and mode) and special
+files are supported if the \fB--unix-data\fR option is used.
+.PP
+However, the following features are \fIunsupported\fR and not exposed in mounted
+images:
.IP \[bu] 4
-Windows security descriptors. These are not exposed in the mounted filesystem,
-although existing values will be preserved on commit. New files are not given
-security descriptors.
+Windows security descriptors. New files are not given security descriptors.
.IP \[bu]
-DOS names (8.3 names) (short names). These are not exposed in the mounted
-filesystem, although existing values will be preserved on commit. New files are
-not given DOS names.
+DOS names (8.3 names) (short names). New files are not given DOS names.
.IP \[bu]
-Windows file attributes. These are not exposed in the mounted filesystem,
-although existing values will be preserved on commit. New files are assigned
-default attributes based on the UNIX file mode bits.
+Windows file attributes. New files are assigned default attributes based on the
+UNIX file mode bits.
.IP \[bu]
-Object IDs. These are not exposed in the mounted filesystem, although existing
-values will be preserved on commit. New files are not given object IDs.
+Object IDs. New files are not given object IDs.
.IP \[bu]
EFS-encrypted files. The files themselves will be visible in mounted WIM images
but their data will not be available.
+.IP \[bu]
+Extended attributes. Although wimlib now supports creating a WIM image
+containing Linux-style extended attributes, these are not yet exposed in mounted
+WIM images. (This may be implemented in the future, though it would conflict
+with the use of extended attributes to expose Windows concepts like named data
+streams.)
.SH SPLIT WIMS
You may use \fBwimlib-imagex mount\fR to mount an image from a split WIM
read-only. However, you may not mount an image from a split WIM read-write.
