@phoronix It really is a double-edged sword.
A win, because generally speaking, better interoperability is good, and making software more portable is good, and if it can improve systemd, the world will be better for it.
A win, because getting to that point proves that musl is finally, at last, being taken seriously by one of the most reluctant players in the ecosystem, so it's a sign that musl is a real, believable alternative now, and it will push more people and projects to try it out.
But also a danger, because it now means that systemd actually sees musl systems as targets. Systems that opted for musl were safe from systemd so far; maintainers were not tempted to switch to it because it was not a technically sound proposition. Now that systemd officially supports musl, no distribution is safe, and the survival of the non-systemd ecosystem now only depends on the technical judgment of distribution maintainers. Which has been subverted before, as Debian has painfully and dishonorably shown.
I would like to say I am cautiously optimistic. But I am actually terrified.
