What is the preferred way to set sysctl variables?

I would like to increase the max file watchers as I am working with large projects that have more than 8192 files: https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc

While I can do this manually every time I start colima, ideally this happens automatically. I thought I could add provision to colima.yml, but it's removed when I run colima start.

For now, your best option is to use the provision section of a Lima override config.
Nonetheless, this should be included in Colima by default and will look at adding it in future releases.

Yeah, this is not yet supported as proper configuration file support is in the works.
Considering the colima primarily generates a Lima config, I do not want to deviate entirely away from that.
