+How to generate/update the file uutils-coreutils_XXX.bb:
+
+cargo with version > 1.60 is needed so cargo from Ubuntu's apt will not work
+(because of https://github.com/rust-lang/cargo/issues/10623):
+This package is needed (tested on Ubuntu 22.04):
+sudo apt-get -y install librust-cargo+openssl-dev
+
+Then install cargo-bitbake with:
+$ cargo install --locked cargo-bitbake
+
+You can now update coreutils:
+$ git clone https://github.com/uutils/coreutils.git
+$ cd coreutils
+$ git tag
+$ git checkout 0.0.XXX
+$ cargo-bitbake bitbake
+Wrote: coreutils_0.0.15.bb
+
+Verify manual changes in the bb file (rename coreutils.inc to uutils-coreutils.inc)
