I have no idea what Systemd wants to do with a birthdate, but what confuses me is that this specifically was merged to comply with californian law.
Does that mean every reasonably sized political entity can now declare some stupid requirement and somebody has to merge it into Systemd, because if California is important enough so are 1000s of other states, nations and so on?

Anyway, version 260 will probably hit the arch repos soon and I can answer the question:
Will I be able to boot my ThinkPad with security features enabled after more than 4 months of it being bugged.

Tbf...ThinkPads are really obscure hardware and never used it environments that might require some security features (actually tbf those probably don't run bleeding edge distros but eh)

The anti systemd crowd seems to slowly start having a point. Still for all the wrong (truly awful) reasons but it ends with the same result.
Welp. This looks promising…
