   - `dmesg | grep "KASLR disabled due to lack of seed"`
   - fix by adding `kaslrseed` to uboot script before `booti`
     - <https://github.com/armbian/build/pull/4352>
-    - not sure how that's supposed to work with tow-boot; maybe i should just update tow-boot
+    - recent u-boot should do this automatically, if DM_RMG=y: <https://patchwork.ozlabs.org/project/uboot/cover/20240618210609.1744727-1-tharvey@gateworks.com/>
+    - this was merged after the v2024.07 merge window
+      but it made it to v2024.10-rc*
   - i think there's a kernel config option for early entropy also
+    - e.g. EFISTUB + EFI_RNG_PROTOCOL
 - newflash on moby can't play videos
   - "open in browser" works though -- in mpv
 - gnome-maps can't use geoclue *and* openstreetmap at the same time
