마운트 지점을 루트로 설정할 수 없나요?

# cd /mnt
# file $(which chroot)
/usr/bin/chroot: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64-ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=1922fc941e62b1cd0954c5fbf22bc37f7ef84870, stripped
# which chroot
/usr/bin/chroot 

# ls /mnt/bin/bash
/mnt/bin/bash
# chroot /mnt mnt/bin/bash
-bash: /usr/bin/chroot: No such file or directory

# cp -a /usr /mnt
# chroot /mnt mnt/bin/bash
- bash: /usr/bin/chroot: No such file or directory

Centos 7을 복구 모드에서 구출하려고 했습니다(데비안 배포판, 호스팅 회사는 이렇습니다). 인터넷에서 가능한 모든 해결 방법을 시도했지만 위 메시지를 chroot받을 수 없습니다./mnt

추신: 나는 마운트, proc, dev 및 sys를 바인딩했습니다.
