I am working with a mercurial repository and switched from installing hg via one package manager (nix) to another (guix).
Now I get the error message
% hg pull
abort: accessing `persistent-nodemap` repository without associated fast implementation.
(check `hg help config.format.use-persistent-nodemap` for details)
And cannot interact with the repo anymore. How can I circumvent hg's attempt at trying to use persistent-nodemap. my repo is a few lines of code and I don't need any performance optimisation.
