Further to above, there are more problems:

- files in /etc/skel were not copied in /home/dev
- dev user password is not saved in /etc/passwd, so I cannot log in 
with that user

These problems do not occur if I create an user within the container:

# useradd test -p testing!
# ls -a /home/test/
.  ..  .bash_logout  .bash_profile  .bashrc
# ls -l /home
drwx------ 2 test test 4096 Jul  5 11:45 test

So it's not a bug in shadow-utils.
It must be something about how mkosi.postinst work. Unfortunately I 
don't have any mkosi examples to look at, in order to find any easy 
mistake I might have done.
