nixpkgs/pkgs/os-specific/linux/systemd/0002-Don-t-try-to-unmount-nix-or-nix-store.patch
nikstur 748378a3ec systemd: 254.6 -> 255.2
Removed patches:

- 0007-Fix-hwdb-paths.patch

  The directory we want seems to already be included in the list. Is there
  a reason why we want to restrict it further?

- 0010-build-don-t-create-statedir-and-don-t-touch-prefixdi.patch

  This patch has little to do with how the meson.build file looks now. The
  new patch 0017 is the successor to this one.

- 0015-pkg-config-derive-prefix-from-prefix.patch

  This is fixed upstream. We don't need this anymore.
