I guess you missed my follow-ups in this thread.
The problem was caused by a file (.bashrc) I placed in 
mkosi.extra/home/dev.
My understanding is that mkosi first copied that file, then run the 
postinst script containing the useradd command, which failed 
(correctly) as /home/dev already existed.

I've moved the file to mkosi.extra/etc/skel and now everything works 
fine.
