Revert "Specify /bin/zsh when creating a new user (#755)"

[ViViDboarder]

This reverts commit 7fd5170.

Proposed Changes

This reverts #755, which introduced a bug preventing the user from switching to root after login. I can see that that PR was intended to fix #788, but there ought to be a proper fix in the way of utilizing the zsh configuration option rather than forcing the default shell to be zsh. If indeed there is a desire to change the default shell, consideration should be taken to make sure other locations expecting sh are updated.

Walkthrough

The changes in this pull request modify the SSH daemon configuration script for the Home Assistant Community Add-on for Advanced SSH & Web Terminal. The primary alteration involves changing the default shell for user accounts from /bin/zsh to /bin/sh when creating users, specifically if the username is not "root." The script retains its existing functionality for SSH key management, security practices, and configuration checks.

Poem

In the land of code where rabbits play,
We changed the shell to brighten the day.
From zsh to sh, a leap we take,
For smoother paths, we make no mistake.
Hopping along, with keys in tow,
Secure and swift, let the SSH flow! 🐇✨

102-102: Approve: Change default shell to /bin/sh

This change from /bin/zsh to /bin/sh addresses the reported issue of users being unable to switch to the root account. Using /bin/sh as the default shell is more universal and less likely to cause compatibility issues.

Consider the following recommendations:

1. Document this change in the add-on's changelog or documentation to inform users about the default shell change.
2. Consider adding a configuration option that allows users to choose their preferred shell (e.g., ssh.default_shell). This would provide flexibility for users who prefer Zsh or other shells.

Example implementation for a configurable shell:

default_shell=$(bashio::config 'ssh.default_shell' "/bin/sh")
adduser -D "${username}" -s "${default_shell}" \
    || bashio::exit.nok 'Failed creating the user account'

This approach would maintain the fix while offering users more control over their environment.
