this converts meta.doc into an md pointer, not an xml pointer. since we
no longer need xml for manual chapters we can also remove support for
manual chapters from md-to-db.sh
since pandoc converts smart quotes to docbook quote elements and our
nixos-render-docs does not we lose this distinction in the rendered
output. that's probably not that bad, our stylesheet didn't make use of
this anyway (and pre-23.05 versions of the chapters didn't use quote
elements either).
also updates the nixpkgs manual to clarify that option docs support all
extensions (although it doesn't support headings at all, so heading
anchors don't work by extension).
Stderr does not exist as a systemd option (StandardError would've been
correct), but since "journal" is the default by association this mistake
never had any effect. just remove the key entirely.
in some circumstances, the setup service would fail with:
ERROR 1062 (23000) at line 5: Duplicate entry '1' for key 'PRIMARY'
so let's use an upsert instead of insert. This also simplifies the
script.
Besides, also fix that when the setup script changes, the corresponding
script is not restarted as it is usually not active, so we trigger a
restart of the main systemd service.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
