+    <braunr> and btw, here is a little update about my roadmap: while reading
+      mcsim's patches, i've got to know libpager a bit more, and i think it's
+      perfectly possible to add writeback throttling without a heavy rework
+    <youpi> good :)
+    <braunr> so i intend to work on that after the pager related patches (large

 This QEMU image is not (yet) comparable to NixOS, because the latter provides
 extra features, such as whole-system configuration (including services, etc.),
 and whole-system transactional update and rollback.  It is is cross-built using
 Nix, and because of that, it uses per-package installation directories under
 `/nix/store`.

+    <youpi> I don't remember which way it works, but iirc depending on whether

+    <youpi> problem being that nothing says linux' clock is 100Hz, but a lot of
