+[[Chezmoi]] supports [[templates]] to special-case files depending on the host they're being installed in.
+
+To apply a template to an already tracked file, e.g. .config/sway/config (in my case):
+
+```
+chezmoi chattr +template .config/sway/config
+chezmoi edit .config/sway/config
+```
+
+Then use template syntax (see https://www.chezmoi.io/user-guide/templating/#simple-logic for the gist of it if you're interested in per-hostname cases, which is what I was after) and then use `chezmoi apply` to "run" the template and produce the file in any host.
+
+Note that you need to edit the file with chezmoi edit every time essentially, unless you intend to get conflicts later. It seems like a fair tradeoff to me.
