I want to delete them because I want to continue experimenting and I want to make sure that none of those files or directories are interferring with my experimentation in any way. I've tried executing the following command, but I get the following error. ,---- | find /gnu/store -mindepth 1 -maxdepth 1 -name '*font-noto-color-emoji*' | xargs guix gc -D | echo Exit code: $? `---- ,---- | finding garbage collector roots... | guix gc: error: cannot delete path `/gnu/store/2j9gykgj0axgg193pd6hvrmnzqbz88nm-font-noto-color-emoji-2.034.drv' since it is still alive | Exit code: 123 `---- Again, I need to delete those files, because I want to learn more about Guix and continue experimenting, so I want to install the package as if it had never been installed in my system. I suppose that some files from previous installations are reused, I don't want this to occur, that's why I want to delete them.
