Enhancement Type Improve an existing feature Describe the enhancement This is a issue extended from the discussion seen here: here. In particular: I do not see a documented path that combines Auto CurseForge managed modpack loader installation with an arbitrary Cleanroom installer. This is blocking issue for me. Consider adding a way of resolving a curseforge pack to a generic pack before the Cleanroom installer is used. Or, recommend a way that I can workaround this issue - I can spend the time to figure out how to convert a curseforge pack to a generic pack manually, but this is a pain, and it's surprising that this flow isn't supported since it is supported without cleanroom. thanks
Enhancement Type A completely new feature Describe the enhancement The ability to call a webhook with a JSON payload upon server shutdown or start up. This would be useful for a status message in something like Discord.
Enhancement Type Improve an existing feature Describe the enhancement It would be great if all features that support downloading from a URL or container path, e.g. WORLD, OPS_FILE, WHITELIST_FILE, ICON, etc. supported getting the respective files from a (private) S3 or bucket or other compatible object storage. An easy workaround is proxying via nginx-s3-gateway or similar, but builtin support seems more straightforward. Thanks for considering!
Enhancement Type Improve an existing feature Describe the enhancement MeowIce provides 2 versions of the flags - one using the standard G1GC and the other using ZGC. ZGC is a latency focused garbage collector which may have some benefits for higher end CPUs in reducing stutters due to garbage collection.
Enhancement Type Improve an existing feature Describe the enhancement It would be awesome if you could implement env var REMOVE_OLD_CONFIGS. Aim is to delete/cleanup all files in config folder on server boot before it downloads the modpack. Why do I need this? Because some mod authors have designed their mod configs badly and have put client and server configurations in single file. Due to that, so that every modpack update wouldn't override client's custom settings, I've moved some of those settings to defaultoptions configs (which are only copied using some specific mods when the file doesn't already exist).
