More possible Cleanup targets

[cmahnke]

Since the Runner VMs are populated by a script, the knowledge of the contents of its configuration can help with identifying further target to remove.
For example:
https://github.com/actions/runner-images/blob/main/images/linux/toolsets/toolset-2204.json

How about either generating the options of this option directly from the JSON file or create some sort of rollback mechanism, than can take a similar script and just remove the software missing from the modified json file?

just my 2 cents

• "linux" seems to have changed to "ubuntu" in your link: https://github.com/actions/runner-images/blob/main/images/ubuntu/toolsets/toolset-2204.json
• seems like a valid approach, meanwhile I've found another

Thanks to everyone who works on this project.
I've looked a little bit deeper today. Based on PR #20 following things to add:

• there is a package google-cloud-cli instead of google-cloud-sdk, but there is a bigger sized folder /usr/lib/google-cloud-sdk
• I reduced the info from this PR a little bit, since that didn't come with my method:

sudo apt-get purge -y '^llvm-.*' azure-cli powershell mono-devel

• The following gets every userinstalled package, filters packages which shouldn't get removed, uninstalls everything not filtered and then cleans up config-files:

removePackages=`apt list --manual-installed | awk '{print $1}' | sed 's|\(.*\)/.*|\1|' | grep -E -v 'base*|bash|binutils|bsdutils|bzip2|ca-certificates|coreutils|curl|dbus|diffutils|dpkg*|file|findutils|git*|grep|gzip|hostname|init|iproute2|iputils-ping|keyutils|lib*|linux-headers*|linux-image*|lld*|locales|login|lsb-release|make|net-tools|openssh-*|openssl|patchelf|rpm|rsync|session-manager-plugin|shellcheck|ssh|sudo|sysvinit-utils|tar|tcl*|time|tk|tzdata|ubuntu-*|unzip|upx-ucl|walinuxagent|wget|xz-utils|zip*|zsync|apt|dash|ncurses-bin|shim-signed|grub-efi-*|mokutil|sbsigntool|secureboot-db|docker-*|containerd.io' | tr '\n' ' '`
echo "Removing following userinstalled packages: $removePackages"
sudo apt-get purge -y $removePackages
sudo apt-get clean && sudo apt-get autoremove --purge -y $(dpkg -l | grep '^rc' | awk '{print $2}') && sudo rm -rf /var/lib/apt/lists/* 

• Keep in mind, that that also removes things like python3 (since I had the specific need I added this to this filter as well) - maybe pass additional-filter string to the script
• There are still dirs you don't need and have lot of data for example /etc/skel (0,5GB) or /usr/local/.ghcup (haskel - some GB), you may or may not delete them, depending on what you need. Some things of them (/etc/skel) will work for (nearly) everyone.
• you may remove containerd.io and docker-* afterwards (if you don't need it), but this action uses docker, so I couldn't remove before

• Doing all of this before your action I'm getting additional 24 GB compared to your main-branch (PR seems to get 5-6 GB additional)

As said that would remove nearly everything (even things like haskell, even if you say haskell:false), therefore this would need more effort to get it into a PR, don't think having enough time in the near future, but maybe someone finds the time (or can use this info)
