ZSTD is a compression algorithm targeting intermediate compression |
| 224 |
with fast decompression speed. It will compress better than GZIP and |
| 225 |
decompress around the same speed as LZO, but slower than LZ4. |

If you choose this, keep in mind that you may need to install the zstd |
| 228 |
tool to be able to compress the initram. |
