Thanks for spotting that. I managed to typo it. Fixed in v2. Stefan

There are two different modes in which @code{rebase} can operate: @table @option
The src_cache option (-T) specifies the cache mode for backing files. It applies both the image's old backing file as well as the new backing file: ret = bdrv_open(&bs_old_backing, backing_name, NULL, NULL, src_flags, old_backing_drv, &local_err); if (ret) { ... } if (out_baseimg[0]) { bs_new_backing = bdrv_new("new_backing", &error_abort); ret = bdrv_open(&bs_new_backing, out_baseimg, NULL, NULL, src_flags, new_backing_drv, &local_err); if (ret) { ... } } The documentation only mentions the new backing file but it really applies to both.
