-File permissions and security descriptors are ignored. The information
-contained in them in an existing WIM will be lost when wimlib writes a WIM file.
-This does not seem to matter for Windows PE, but this means that you should not
-use this program to image a drive containing Windows Vista/7/8 and expect it to
-be applied with the correct file permissions.
+Wimlib cannot add security data when it captures a WIM file, although it will
+preserve security data for existing WIM files. New files added to a mounted
+WIM will be added without security data. This does not seem to matter for
+Windows PE, but this means that you should not use this program to image a drive
+containing Windows Vista/7/8 and expect it to be applied with the correct file
+permissions.
