So I managed to modify the lookaside_upload script to support SHA512 hashes. Previously I forgot to change one instance of sha1sum to sha512sum causing the failure I mentioned in my previous email. It'd still be nice if the script was changed to support SHA512 hashes natively though.

Hi,
Recently there was an announcement that the "flat" layout can now be used by SIGs that want to pull in changes from the Fedora RPM repos directly. I'm trying to switch the hyperscale branches for the systemd RPM to use the "flat" layout but I'm running into issues trying to upload the systemd tarball to the CentOS lookaside cache.
I've successfully used the lookaside_upload script from centos-git-common to upload tarballs for use with the rpmbuild metadata layout before, but I'm struggling to get it to work with the "flat" layout. The main issue comes from the fact that in the "flat" layout, the sources file is used which contains a SHA512 hash that's used to find the corresponding tarball in the centos lookaside cache. However, the lookaside_upload script tries to upload tarballs to the lookaside cache using the sha1sum of the tarball as the identifier. This leads to CBS not finding the tarball when trying to do a build.
I tried modifying the lookaside_upload script to use sha512sum instead of sha1sum but when doing this, I get a 500 HTTP internal error from the lookaside cache (https://paste.centos.org/view/5e7ef15c).
Any other way to upload a tarball under the SHA512 identifier to the lookaside cache?
