Arch Linux

if you create a user which uses the "correct" path of /usr/bin/bash you cannot login due it not being in /etc/shells.

adding /usr/bin/bash to /etc/shells solves this.

users with login shell set to /bin/bash cannot login with just /usr/bin/bash in /etc/shells. so both need to be added to keep them compatible.

I see that dash adds /bin/dash to shells. zsh adds /usr/bin/zsh, but doesn't remove /bin/zsh if it exists.

a quick solution is to add both bash paths to /etc/shells in the filesystem package, and update dash to add the new path without removing the old.
