[Buildroot] [PATCH 6/7] package/zsh: add /bin/zsh to /etc/shells

[Yann E. MORIN <yann.morin.1998@free.fr>]

Romain, All,

On 2018-01-14 22:03 +0100, Romain Naour spake thusly:
> When zsh is selected, /bin/zsh is not added to /etc/shells
> (see man shells). So, login tools like dropbear reject the ssh
> connexions for users using zsh as shell in /etc/passwd.
> 
> buildroot authpriv.warn dropbear[853]: User 'kubu' has invalid shell, rejected
>

The usual dance here... ;-)

    ZSH_POST_INSTALL_TARGET_HOOKS = \
        ZSH_TARGET_INSTALL_FIXUPS \
        ZSH_INSTALL_ADD_ZSH_TO_SHELLS

Although I wonder if we don;t in fact prefer to assign right after the
definition if the hooks...

    define ZSH_INSTALL_ADD_ZSH_TO_SHELLS
        grep -qsE '^/bin/zsh' $(TARGET_DIR)/etc/shells \
        || echo "/bin/zsh" >> $(TARGET_DIR)/etc/shells
    endef
    ZSH_POST_INSTALL_TARGET_HOOKS = ZSH_INSTALL_ADD_ZSH_TO_SHELLS

    # Remove versioned zsh-x.y.z binary taking up space
    define ZSH_TARGET_INSTALL_FIXUPS
        rm -f $(TARGET_DIR)/bin/zsh-$(ZSH_VERSION)
    endef
    ZSH_POST_INSTALL_TARGET_HOOKS += ZSH_TARGET_INSTALL_FIXUPS

Note that we register before the existign hook, but use a simple
assignment, so that we don;t need to change the xisting append-assign to
a simple assign...

Regards,
Yann E. MORIN.
