Would it be possible to expand the support to aarch64 (I can confirm it compiles without problems)?

Any AUR helper is unofficial. You need to fill bug report to paru.

Hello, I get this error message when running in paru:

uutils-coreutils ... Skipped docs.tar.zst ... FAILED ==> ERROR: One or more files did not pass the validity check! error: failed to download sources for 'uutils-coreutils-git-0.7.0.r46.gde5e4f5-1': error: packages failed to build: uutils-coreutils-git-0.7.0.r46.gde5e4f5-1

It works fine with makepkg though. I hope this helps. Thanks

Updated. But makepkg works with bash. Nothing to do for zsh.

2 issues

1. in zsh makepkg [ $RUSTC_BOOTSTRAP = 1 ] - syntax error
2. check b2sums fails for docs

-git is drop-in for coreutils currently. But you can just pacman -S coreutils to recover.

Thought I could just literally run ln -s /usr/bin/uu-coreutils /usr/local/bin/NAME and be done with it, I then force uninstalled coreutils-uutils and was left without any coreutils. If this happens to anyone else, run this as root or with sudo in bash to fix it:

utils=(/usr/bin/uu-*)
for i in "${utils[@]}"
do
     uu-ln -s "$i" "/usr/local/bin/$(sed -e 's/\/usr\/bin\/uu-//g' <<< "$i")"
done

sed isn't part of coreutils, but if you only have uutils-sed as well just replace sed with uu-sed
