I did :( I thought runtime support was there also, my mistake. But it would be nice to be able to control compression in run time. I think there is some preparation already in place for that via chattr?) Perhaps it would be enough to be able to mark selected directories at mkfs time. > > If it helps you I can provide an unofficial proc interface support. > Using it you will be able to change the compression mode - but not only > for a directory but globally.
