+\fB--no-acls\fR
+Do not capture files' security descriptors. This option is available in the
+Windows version, as well as on UNIX in NTFS capture mode.
+.TP
+\fB--strict-acls\fR
+(Windows only) Fail immediately if the full security descriptor of any file
+cannot be read. The default behavior without this option is to first try
+omitting the SACL from the security descriptor, then to try omitting the
+security descriptor entirely. The purpose of this is to capture as much data as
+possible without always requiring Administrator privileges. However, if you
+desire that all security descriptors be captured exactly, you may wish to
+provide this option, although the Administrator should have permission to read
+everything anyway.
+.TP
+\fB--rpfix\fR, \fB--norpfix\fR
+Set whether to fix targets of absolute symbolic links (reparse points in Windows
+terminology) or not. When enabled (\fB--rpfix\fR), absolute symbolic links that
+point inside the directory tree being captured will be adjusted to be absolute
+relative to the root of the directory tree being captured. In addition,
+absolute symbolic links that point outside the directory tree being captured
+will be ignored and not be captured at all. When disabled (\fB--norpfix\fR),
+absolute symbolic links will be captured exactly as is.

+The default behavior for \fB@IMAGEX_PROGNAME@ capture\fR is equivalent to
+\fB--rpfix\fR. The default behavior for \fB@IMAGEX_PROGNAME@ append\fR will be
+\fB--rpfix\fR if reparse point fixups have previously been done on
+\fIWIMFILE\fR, otherwise \fB--norpfix\fR.
+.IP ""
+In the case of a multi-source capture, (\fB--source-list\fR specified), passing
+\fB--norpfix\fR is recommended. Otherwise, reparse point fixups will be
+disabled on all capture sources destined for non-root locations in the WIM
+image, while capture sources destined for the WIM root will get the default
+behavior from the previous paragraph.
