There is one more feature that zram can do: multiple compression levels. I use simple bash script to first use fast compression and after 1h recompress it using much stronger compression. unfortunately you cannot chain it with any additional layer or offload to disk later on, because recompression breaks idle tracking by setting timestamp to 0 (so it's 1970 again) https://gist.github.com/Szpadel/9a1960e52121e798a240a9b320ec13c8 https://gist.github.com/Szpadel/9a1960e52121e798a240a9b320ec...
