Now kimchi uses host system users to login.
In fedora most of system users are not allowed to login. so we should
filter them.
but in ubuntu, it seems most system user still can login. but their
pw_shell are /bin/sh it is softlink to */bin/bash
*
Now I'd like to just list the users who's pw_shell are /bin/bash
Not sure all distribution can works well by this way.
I have just checked fedora and ubuntu, seems it can works.
so any one can help check if any exception on your distribution?
