Supersedes #28721

When managing geth over docker, sometimes it's desirable to do a partial wipe: delete state but retain freezer data. This can be a bit tricky: the ansible scripts to delete files individually are slow, a faster way to do it is to

  • move the freezer-data somewhere else,
  • delete the chaindata
  • create the chaindata
  • move back the freezer-data

This "works" but it's clumsy, and now that we have both block-data and state-data in freezer, it's a bit incomplete, the correct thing to do would be to save only the block-data, not the state-data.

This PR implements an alternative way to achieve the same thing, by making it possible to run geth removedb non-interactive, using boolean options instead.


Explicitly removing chain (it asks about state, no question about chain):
