I hardcoded compression level 10. On my system it compresses the initramfs I generated under a second. Numbers from my testing: * ugrd.cpio is 20MB * ugrd.cpio.xz is 6.2MB * Compression takes 14s * Decompression takes 0.5s * ugrd.cpio.zst is 7.5MB * Compress takes 0.88s * Decompression takes 0.08s

Thank you! I think I will add some tests for this. One thing I've been considering is how the compression level should be specified. I tried to make the compression option somewhat open ended (despite being somewhat hardcoded for xz) and wasn't sure how to generalize compression levels for various algorithms. |

I added a compression level setting here, and tried to generalize the imports a bit more, with improved error messages on failed imports. |
