Description Lance Albertson 2021-06-01 23:28:39 UTC 
Description of problem:

Currently CentOS Stream rebuilds the ISO images weekly and only keeps one ISO image. These ISO images have the dates included which makes image automation using tools such as Packer difficult. This was discussed on the CentOS devel mailing list [1] with a possible solution of adding a "latest" symlink along with including those files in the CHECKSUM file. That way, we can set one filename that will stay consistent.

Ideally, I'd like to see the following (as an example):

CentOS-Stream-8-x86_64-20210528-boot.iso
CentOS-Stream-8-x86_64-20210528-boot.iso.manifest
CentOS-Stream-8-x86_64-20210528-dvd1.iso
CentOS-Stream-8-x86_64-20210528-dvd1.iso.manifest
CentOS-Stream-8-x86_64-latest-boot.iso
CentOS-Stream-8-x86_64-latest-boot.iso.manifest
CentOS-Stream-8-x86_64-latest-dvd1.iso
CentOS-Stream-8-x86_64-latest-dvd1.iso.manifest

And CHECKSUM should look like the following:

# CentOS-Stream-8-x86_64-20210528-boot.iso: 758120448 bytes
SHA256 (CentOS-Stream-8-x86_64-20210528-boot.iso) = d8019b18e1f09bcd89b5e68c7ed9d40e87df28582e4f1c36782e66c581a97b95
# CentOS-Stream-8-x86_64-20210528-dvd1.iso: 9960423424 bytes
SHA256 (CentOS-Stream-8-x86_64-20210528-dvd1.iso) = eb9de263b41e2a4a4c514ef99572c4e070b742dee6369c430ab2a0d869fc2ec2

# CentOS-Stream-8-x86_64-latest-dvd1.iso: 9960423424 bytes
SHA256 (CentOS-Stream-8-x86_64-latest-dvd1.iso) = eb9de263b41e2a4a4c514ef99572c4e070b742dee6369c430ab2a0d869fc2ec2

I've modified our staging scripts to create latest symlinks and include them in the CHECKSUM file.

Give this a little time to sync out to the mirrors, then give it a shot in your tooling to see if it works for you.
