I remember unpacking their builds a while ago out of curiosity, and it was based on LFS with a few spec files borrowed from Photon and Fedora. I wonder if switching the base to actual Fedora will increase bloat, it's super lightweight right now.
Interestingly, this is pretty much what amazon did with amazon linux 2023.
It’s also noteworthy that amazon had promised more frequent release of amazon linux moving forward, but afaik there is no significant release after 2023 (i’d be happy to be proven wrong)
