dotfiles/README.md

Lines 97 to 117 in 0b86d5a

	### Podman on Ubuntu
	1. Install uidmap without Nix for use of podman even if the podman will be installed from nixpkgs
	- "shadow" in nixpkg is not enough for podman - <https://github.com/NixOS/nixpkgs/issues/138423>
	```bash
	sudo apt-get install --assume-yes uidmap
	```
	1. Make sure putting /etc/containers/policy.json, it is not a home-manager role
	```bash
	sudo mkdir -p /etc/containers
	cd /etc/containers
	sudo curl -OL https://raw.githubusercontent.com/kachick/dotfiles/main/config/containers/policy.json
	```
	1. Make sure the cgroup v1 is disabled if you on WSL, See [the docs](windows/WSL/README.md)
	1. Make sure you can run containers as `podman run public.ecr.aws/debian/debian:12.6-slim cat /etc/os-release`

Looks like the module also requires uidmap via apt. So I don't have confidence using it makes things simpler than now. https://github.com/nix-community/home-manager/pull/4801/files#diff-05eb87a6abb8c5d69f9b58ca41961c9039d06097eab947dcef54ee61c40520aeR122-R129
