If that's desired, then yes, my patch isn't a good solution.

I guess one real issue is that mkpasswd on redhat fails and returns an empty
hash, which is inserted into the shadow file.
Maybe the thing to do to work across distros would be to compile the correct
mkpasswd as a host- package?
In the meantime I think your suggestions of using a custom overlay or post build
script should work great.
