Linux系统维护必备命令－－chroot

  
  
  
  

   
   
   
   
 
    mount /dev/sdx /mnt/gentoo 
   
   
   
   
   
 
    mount -t proc none /mnt/gentoo/proc/ 
   
   
   
   
   
 
    或 
   
   
   
   
   
 
    mount -t proc proc /mnt/gentoo/proc/ 
   
   
   
   
   
 
    mount --rbind /sys /mnt/gentoo/sys/ 
   
   
   
   
   
 
    mount --rbind /dev /mnt/gentoo/dev/ 
   
   
   
   
   
 
    mount --rbind /tmp /mnt/gentoo/tmp (gentoo) 
   
   
   
   
   
 
    可选：mount --rbind /run /mnt/arch/run (arch) 
   
   
   
   
   
 
    DNS: cp /etc/resolv.conf etc/resolv.conf 
   
   
   
   
   
 
    chroot /mnt/gentoo /bin/bash 
   
   
   
   
   
 
    env-update (gentoo) 
   
   
   
   
   
 
    source /etc/profile 
   
  
  
  
  

Optionally, create a unique prompt to be able to differentiate your chroot environment:

  
  
  
  

   
   
   
   
 
    export PS1="(chroot) $PS1"
