+- `2e107e5` **fix: LED driver for every kernel on a fresh install**
+  - The DKMS override was written to `/etc/dkms` before `dkms` was installed,
+    when that folder doesn't exist yet, so it silently failed and the build
+    for other kernels (e.g. LTS) failed as in 0.6. The folder is created first
+    now, and a failed write stops with an error.
+- **feat: Restart question on quit is "Restart now? [Y/n]"**
+  - When something needs a restart, `q` asks with yes as the default; `n` goes
+    back to the menu and the next `q` asks again. Ctrl+C quits without
+    restarting; scripted input that runs out never restarts.
