Points compose to fix/backup-compose-os-upgrade which:
- restic/restic -> restic/rest-server
- embergarage/restic-browser -> floibach/restic-browser
- adds persistent browser-data volume
- adds backup/.env with RESTIC_PASSWORD

+#
+# clamav:
+#   cmake try_run() + Rust proc-macro can't find native linker in
+#   cross-compile (cc crate uses cross CC, no cc in PATH for build
+#   scripts). Chain: clamav → system-path → etc → dbus → polkit.
+#   Fix: remove from system packages; clamscan available from server.
+
+#
+# ==== Remote builder setup (bidirectional) — TODO ====
+# To eliminate cross-compile exceptions, set up distributed builds:
+# 1. Create a dedicated `builder` user on both hosts (no shell, home=/var/empty)
+# 2. Add the same SSH key to both hosts (symmetric)
+# 3. On lazyworkhorse — `nix.buildMachines` pointing to uConsole for aarch64-linux
+# 4. On uConsole — `nix.buildMachines` pointing to lazyworkhorse for x86_64-linux
+# 5. Remove the uconsoleCrossOverlay workarounds above
+# 6. Nix auto-dispatches derivations by `system` — no per-package exceptions needed
+# Example buildMachines config:
+# Server dispatches aarch64 builds to uConsole (4 cores, less power):
+#   nix.buildMachines = [{
+#     hostName = "uConsole.local";
+#     systems = ["aarch64-linux"];
+#     maxJobs = 4;
+#     sshUser = "builder";
+#     sshKey = "/etc/ssh/builder_key";
+#   }];
+# uConsole dispatches x86_64 builds to server (36 cores, 256GB RAM):
+#   nix.buildMachines = [{
+#     hostName = "lazyworkhorse.net";
+#     port = 2424;
+#     systems = ["x86_64-linux"];
+#     maxJobs = 36;
+#     sshUser = "builder";
+#     sshKey = "/etc/ssh/builder_key";
+#   }];
+
+      # ==== How to build natively on uConsole ====
+      # To native-compile these on the uConsole:
+      # 1. Add uConsole as a remote builder (nix.buildMachines)
+      # 2. Set nix.extra-platforms = [ "aarch64-linux" ] on server
+      # 3. Remove the overlay workarounds below
+      # 4. Packages will auto-dispatch to uConsole for native builds
