How do I move the mount point of a drive

Question

I have /dev/sda2 mounted as /mnt. I am actually running my system from a volume mounted at /mnt/install (I've chrooted to /mnt/install).

I'd like to be able to use that disk from within my chrooted linux. How do I move /dev/sda2 from /mnt to /mnt/install/mnt/fast?

Answer 1

Is your chrooted system inside /dev/sda2? if not, just create that folder and mount to it

Outside the chroot enviroment,

first, unmount the current folder

sudo umount /mnt/install

then, make the new mount point directory

sudo mkdir -p /mnt/install/mnt/fast

finally re-mount the partition to your new mountpoint

sudo mount /dev/sda2 /mnt/install/mnt/fast

now, you should be able to chroot and access files at /mnt/fast
