Create parent directories for <user> home

[ampresent]

Problem description

Add a new user and assign it with a new home directory through.
<user name="newuser" home="/path/to/home"/>
Kiwi fails to create image when /path/to/ doesn't exist,
because useradd -m -d /path/to/home newuser assumes /path/to/ exists.

Expected behaviour

Kiwi creates /path/to/home automatically and assign it to newuser.

Steps to reproduce the behaviour

• Ensure /path/to doesn't exist
• Add a line <user name="newuser" home="/path/to/home"/> in appliance.kiwi
• Build a image
• Kiwi fails

OS and Software information

• KIWI version:
• Operating system host version: RockyLinux 9.2
• Operating system target version: CentOS 8.5
• Open Build Service version (N/A if not using OBS): N/A
• Koji version (N/A if not using Koji): N/A

It's interesting that you run into that issue because

• standard users has their home below /home which always exists according to FHS
• non standard users, daemons and others usually provide their user setup through a package

You should be able to workaround the issue by creating the parent in a config.sh script of your image description.
But I would be interested which use-case triggered the problem in the first place

No objections to make sure kiwi creates the parent though
