i saw NETRUNNER debian release is installed with plymouth support. and you can choose various netrunner bootsplash in plasma system settings.
but why no plymouth support given for rolling release ? Please stop treating arch rolling release as second class citizen. we need bootanimation support asap. :@ :@ … 
Plymouth is not supported in arch or Manjaro, thus we do not have it either.
Besides, it was the cause of too many boot issues to begin with.
Manjaro is working on incorporating an alternative that should be great once it’s ready, patience…
ok sir…thanks for the clarification. debian is not my favourite but sadly its ahead in fixing bootanimation issues. hope manjaro fix it soon.
