Will you have to reflash Ubuntu Touch or Lineage after an update? It was mentioned on an UBTalk that the slot switching method of dual booting is rather hacky and could give rise to issues upon updating. I'd say this is only for those that are brave of heart or like to thinker, not necessarily for usages as a daily driver.
Has anyone had issues with a similar setup? I find this solution to dual booting cool, but would also like to figure out the limits of this setup. 🙂
