We should keep /bin/zsh as the canonical path into /etc/shells (and sheebangs).
/bin is the legacy default path for all shells we have.
Changing it will only introduce incompatibility and lack of understanding.

By example with chsh:

# chsh
Changing shell for root.
New shell [/bin/zsh]: /bin/zsh
chsh: Warning: "/bin/zsh" is not listed in /etc/shells.
chsh: Shell not changed.
This task depends upon

Right now we have bash that can only be /bin/bash and zsh that can only be /usr/bin/zsh.

Confusing? Hell yeah.

Edit: I just took a look at the install files for shells I could find in the main repos. Currently in /etc/shells, we have:

/bin/sh
/bin/bash
/bin/dash
/bin/mksh
/bin/tcsh
/bin/csh

/usr/bin/fish
/usr/bin/zsh

I would correct the purpose of this bug report. We should harmonize our paths in /etc/shells. Use the both (/usr/bin and /bin) or one of both for all but not a mix of them.

I got today pam issues today with box with /bin/zsh in /etc/passwd avoiding login as root... The pam logs was not really verbose and helpful.

Thinking of libnss (ldap or sql) backends which most of time use /bin/shell. The best solution seems to have the both path for all shells.

When using grml-zsh-config $SHELL is set to /bin/zsh. The fact that this is not included in /etc/shells leads to issues e.g. when running pkexec:

The value for the SHELL variable was not found the /etc/shells file
This incident has been reported.

good point; will add both paths then.
