I think that I now have enough information to use this as where I make the rocksdb guide.

I've been missing an ldflags thing when I build with rocksdb.

I've got enough info now to guide users trhough "the right way"

[faddat]

To get this in, I'm going to mark this as ready for review and bundle docs with #876

[ValarDragon]

Sorry didn't notice this getting marked ready for review, my bad

[faddat]

@ValarDragon no problem.

I think I should close this for now, and focus on work upstream to make state sync work with wasm

I know you've been really busy, here's what we are up to right now, I reckon it can/will affect osmo later:

cosmos/cosmos-sdk#11096 (comment)

Thanks for the info! Hyped for getting state syncing and rocksDB working!
