-# 🧹 Sysroot Cleaner
+# Sysroot Cleaner
 
-A tool to clean up sysroots for Linux embedded devices in order to save storage space.
+A tool to clean up sysroots for Linux embedded devices to save storage space.
 
-Here by sysroot we mean the final _target system_ filesystem, rather than the _staging folder_ potentially containing intermediate cross-compilation byproducts.
-
-## What does it do?
-
-_Sysroot cleaner_ is a simple tool used to remove unnecessary files from a target folder which is holding the filesystem of an ELF-based OS (such as Linux). This can for instance be either a cross-compiled device target tree, or a folder being prepared for a local chroot jail. It recurses across all subfolders **part of the same filesystem** and looks for files that can be safely removed to reduce space usage.
-
-The full list of found files is passed to a few modules (aka "cleaners") that can decide whether to keep or remove a specific file. These are:
-
-* **dso**: maps all ELF files and their library dependencies to a directed acyclic graph. For each library, remove it transitively if unreachanble from any executable binary. **Note**: Libraries that are dynamically opened at runtime need to be manually allow-listed. If there is interest, we might support [.note.dlopen](https://github.com/systemd/systemd/blob/main/docs/ELF_DLOPEN_METADATA.md) as it gains more widespread adoption.
-* **allow-/block-list**: given a file of [gitignore patterns](https://git-scm.com/docs/gitignore#_pattern_format), either mark the file for keeping (if in the allowlist) or for removal (if in the blocklist).
-
-## Commandline Options
-
-Usage: `sysroot-cleaner [option…] <sysroot>`, where `<sysroot>` is mandatory, and the path to the root of the sysroot to clean up.
-
-Options can be:
-
-* `-n`, `--dry-run`: Simulate operations without carrying them out.
-* `--split-to <dir>`: Instead of simply removing files, move them to the given location, preserving their relative folder structure.
-* `--allowlist <file>`: An allowlist of files to keep, in `.gitignore` format. Can be passed multiple times. **Note**: this will take precedence over all other removal decisions.
-* `--blocklist <file>`: A blocklist of files to remove, in `.gitignore` format. Can be passed multiple times.
-* `--output-dotfile <file>`: An optional path to save the file graph of the DSO cleaner in GraphViz format. Useful for debugging.
-* `--ld-path <dir>`: An additional path to consider when resolving libraries, relative to the sysroot root. Its behavior is similar of the one of the `LD_LIBRARY_PATH` environment variable when specified to the dynamic linker.
-
-The log level can be controlled via the `LOG_LEVEL` environment variable, and can be one of: `error`, `warn`, `info`, `debug`, `trace`, or `off` (run completely silent).
-
-## Example Usage
-
-Assume that you have built a filesystem image, for instance through a tool like [buildroot](https://buildroot.org/downloads/manual/manual.html).
-
-You could add a simple shell script to invoke `sysroot-cleaner`:
-
-```bash
-#!/bin/bash
-
-# file: post_build.sh
-
-set -e -o pipefail
-
-readonly SCRIPT_DIR=$(realpath "$(dirname $0)")
-readonly TARGET_DIR=$1
-
-if [ ! -d "${TARGET_DIR}" ]; then
-    echo "Expecting the rootfs folder as first argument"
-    exit 1
-fi
-
-# Base lists
-allow_lists=("${SCRIPT_DIR}/base.allowlist")
-block_lists=("${SCRIPT_DIR}/base.blocklist")
-
-LOG_LEVEL=info sysroot-cleaner \
-    $(printf -- '--allowlist %s ' "${allow_lists[@]}") \
-    $(printf -- '--blocklist %s ' "${block_lists[@]}") \
-    "${TARGET_DIR}"
-```
-
-Then, you can set `BR2_ROOTFS_POST_BUILD_SCRIPT` to invoke `post_build.sh`.
-
-## Changelog
-
-### v1.0.0
-
-* Initial stable release.
+Note: it will only work on files belonging to the same filesystem. This is a design choice.
