blfs（systemv版本与systemd版本均适用）学习笔记-从主机挂载lfs的方法

运行如下命令，挂载并进入lfs分区便可

su

export LFS=/mnt/lfs

mount -v -t ext4 /dev/sda6 $LFS       
mount -v -t ext4 /dev/sda5 $LFS/boot   
mount -v -t ext4 /dev/sda7 $LFS/home
  
mount -v --bind /dev $LFS/dev

mount -vt devpts devpts $LFS/dev/pts -o gid=5,mode=620
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
mount -vt tmpfs tmpfs $LFS/run

if [ -h $LFS/dev/shm ]; then
  mkdir -pv $LFS/$(readlink $LFS/dev/shm)
fi

chroot "$LFS" /usr/bin/env -i          \
    HOME=/root TERM="$TERM"            \
    PS1='(lfs chroot) \u:\w\$ '        \
    PATH=/bin:/usr/bin:/sbin:/usr/sbin \
    /bin/bash --login

须要更改的内容：

sda10改成机器为lfs的根分区

sda9改成为lfs的boot分区

sda11改成lfs的home分区

退出chroot并卸载lfs分区的方法

exit 

umount -v $LFS/dev/pts
umount -v $LFS/dev
umount -v $LFS/run
umount -v $LFS/proc
umount -v $LFS/sys
umount -v $LFS/boot
umount -v $LFS/home
umount -v $LFS
