   Please describe the feature you’d like to see added.

   While preparing the little ter.gz file for https://github.com/fjahr/test_chain_init/issues/1 I stumbled upon the fact that one is unable to download just a couple of blocks in the beginning without synchronizing the full header chain.

   I would be happy if the stopatheight option was respected also header-wise. This is a feature request.

   Using 28.0 x86_64 Linux release binaries from bitcoincore.org

   0$ bitcoind -help -help-debug | grep -A 2 stopatheight
   1  -stopatheight
   2       Stop running after reaching the given height in the main chain (default:
   3       0)
   

   Version tested:

    0 bitcoind -version
    1Bitcoin Core version v28.0.0

   For what would you need to use this kind of feature? This probably wouldn’t be as simple to implement as current -stopatheight (one would need to keep downloading blocks after the last header was received but not accept any more headers), so I think that there should be a serious use case.

   Does the hidden debug-only -minimumchainwork=0 not work for this use case?

   Thank you @maflcko ! The minimumchainwork=0 does exactly what I was looking for.

   Closing as solved.
