+## No boot splash

+`plymouth` is deliberately not on either list. Blob configures no splash: there
+is no mkinitcpio hook, no kernel command line, and `default/plymouth/` ships no
+theme assets, so `blob-plymouth-set` has nothing to publish either. An installed
+but unconfigured plymouth is not harmless - it takes the console at boot and
+never hands it back, and `getty@tty1` waits on `plymouth-quit-wait.service`, so
+the machine reaches neither the greeter nor a TTY.
+
+`install.sh` masks `plymouth-start.service` and `plymouth-quit-wait.service` for
+that reason, which un-breaks a machine that already has the package. To go
+further:
+
+```
+sudo pacman -Rns plymouth
+```
