I have rechecked.
It doesn't work with sudo also.
Not in a one line, not when i tried to make line breaks with \, not in a bash script.
user@debian:~$ sudo for i in /dev /dev/pts /proc /sys /sys/firmware/efi/efivars /run; do mount -B $i /mnt/$i; done
bash: syntax error near unexpected token `do'
user@debian:~$ sudo bash bash.sh
mount: /mnt//dev: mount point does not exist.

Sorry, but I can not spot anything apparently incorrect. Did you try to
execute the compound shell command by adding just "sudo" in front of it?
With leading "#" it is assumed that it is already a root shell (obtained
by e.g. "sudo -i") and in this case it is important.
