挂载多分区img镜像方法

需求

备份全盘img镜像需要挂载读取部分内容
镜像含有多个分区无法直接mount

解决

# map image to multiple disk partition
kpartx -av disk.img

# mount the partition you want
sudo mount -o loop /dev/mapper/loop1p1 /mnt/rootfs

# Delete partition mappings after use
kpartx -d disk.img

参考

Ubuntu Manpage: kpartx - Create device maps from partition tables.
