why

sh: 0: Refusing to exec make-arch_drv.sh from noexec mount; see https://chromium.googlesource.com/chromiumos/docs/+/master/security/noexec_shell_scripts.md

To fix this error, copy the file to /var/ then execute the file in /var/
For example
cd /tmp
git clone https://github.com/altreact/archbk.git
cd archbk
cp make.sh /var
sh -c "$(cat /var/make.sh)"
sorry for my poor explanation
