\fB--solid-chunk-size\fR=\fISIZE\fR
-Like \fB--chunk-size\fR, but set the chunk size used in solid blocks. See the
+Like \fB--chunk-size\fR, but set the chunk size used in solid resources. See the
documentation for this option to \fBwimlib-imagex capture\fR (1) for more
details.
.TP
\fB--solid-compress\fR=\fITYPE\fR[:\fILEVEL\fR]
-Like \fB--compress\fR, but set the compression type used in solid blocks. See
+Like \fB--compress\fR, but set the compression type used in solid resources. See
the documentation for this option to \fBwimlib-imagex capture\fR (1) for
more details.
.TP
\fB--not-pipable\fR
Rebuild the WIM in the non-pipable format. (This is the default if
\fIWIMFILE\fR is not pipable.)
+.TP
+\fB--unsafe-compact\fR
+Compact the WIM file in-place, without using a temporary file. Existing
+resources are shifted down to fill holes and new resources are appended as
+needed. The WIM file is truncated to its final size, which may shrink the
+on-disk file. THIS OPERATION CANNOT BE SAFELY INTERRUPTED! If the operation is
+interrupted, then the WIM file will be corrupted, and it may be impossible (or
+at least very difficult) to recover any data from it. Users of this option are
+expected to know what they are doing and assume responsibility for any data
+corruption that may result.
.SH NOTES
\fBwimlib-imagex optimize\fR does not support split WIMs.

+Rebuild and recompress the WIM file 'install.wim', using LZX ("maximum")
compression at a higher-than-default compression level. The compression chunk
size remains unchanged. This command will be slow, but it might be useful for
