pennae 16102dce2f nixos/*: replace <code> in option docs with <literal>
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.

the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").

Wrap the binaries in firejail and place them in the global path.
You will get file collisions if you put the actual application binary in
the global environment (such as by adding the application package to
<literal>environment.systemPackages</literal>), and applications started via
.desktop files are not wrapped if they specify the absolute path to the
binary.
