zsh compinit: insecure directories ... for root only

[n0valis]

Good day,
As I source "${ZINIT_HOME}/zinit.zsh" I get the complaint above (only for root). I checked a lot of recommendations regarding permissions but nothng helped.
compaudit does not produce any output.
$HOME = root,
$ZINIT_HOME = /root/.local/share/zinit/zinit.git
in my .zshrc first thing I am running is source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
then
ZINIT_HOME="${XDG_DATA_HOME:-$HOME/.local/share}/zinit/zinit.git"
if [ ! -d "$ZINIT_HOME" ]; then
mkdir -p "$(dirname $ZINIT_HOME)"
git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
fi
source "${ZINIT_HOME}/zinit.zsh"
If I comment out source "${ZINIT_HOME}/zinit.zsh" I don't get the message.
I made some clean installs of zinit

Any ideas where to look further?
