The kernel debuginfo packages on Fedora, Debian, and Ubuntu, and many of
their downstreams, are all compressed with xz in multi-threaded mode,
which allows random access. We can use this to bypass the full archive
extraction and dramatically speed up kernel debuginfo requests

In order to extract a file from a seekable archive, we need to know
where in the uncompressed archive the file data starts and its size.
Additionally, in order to populate the response headers, we need the
file modification time (since we won't be able to get it from the

we intentionally avoid using it. Specifically, it sometimes takes
