[Suggestion] change home user on /etc/passwd when clone

[mufigilang]

Sorry my english quite bad, tried my best to convey my experience

Is your feature request related to a problem? Please describe.
Yesterday, i'm cloning my ubuntu box, it has custom home directory /home/mufi/dev-box. I also set custom home dir for the new box /home/mufi/Boxes/development-box and move all my home files to the new one, including .ssh directory.

After that i tried to clone my repo from github on my new box. It works!!!, but i got this error
Could not create directory '/home/mufi/dev-box/.ssh' (No such file or directory).
Failed to add the host to the list of known hosts (/home/mufi/dev-box/.ssh/known_hosts).

Then i try to create new ssh key, but the prompt suggest me to save it to /home/mufi/dev-box/.ssh/

Curious, i check my $HOME, it point to /home/mufi/Boxes/development-box, so it's correct.
then i check my /etc/passwd with cat /etc/passwd | grep mufi and it output this mufi:x:1000:1000::/home/mufi/dev-box:/bin/bash.
It still point to the old home dir, so i have to changed it manually.

Describe the solution you'd like
it will be cool if home dir on /etc/passwd can be changed when cloning with custom home directory

Describe alternatives you've considered
I don't really know, i'm linux noob.

Additional context
Anyway thanks for creating this, i'm not really well versed on docker so this is a god send. Really help me in big way.
