How to increase vm.max_map_count?

Question:

I am trying to increase vm.max_map_count, but I don’t know how to do it in replit. The normal recommendation is to modify sysctl like the following:

sysctl -w vm.max_map_count=1000000

But I receive an error that it is ignored and the file system is read only. I’m guessing if I can modify it, it would exist in replit.nix.

Is there a way to configure max_map_count in replit?

Probably not. Most of the configuration and stuff in root is read only.
replit.nix is for the nix env which concerns packages.
There is no configuration for that in the .replit file according to the docs.
I don’t think replit would allow you to just increase the amount of memory that can be used for a program.
