It doesn't work with sudo also.
Not in a one line, not when i tried to make line breaks with \, not in a

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.
dmesg(1) may have more information after failed mount system call.
