Package: user-setup Tags: patch Severity: wishlist Dear Maintainer,
It would be useful to allow preseeding the user shell.
The use case we have at work is building live Debian images and
shipping them to users, where we need to have something other than bash
as the live user shell.
This could be achieved with hacky posthook scripts that sed
/etc/passwd, but it just feels wrong :-)
Attached is a very small and simple patch to add a passwd/user-shell
configurable option, modeled after passwd/user-uid.
Thank you!
Kind regards,
Luca Boccassi

Subject: [PATCH] Add passwd/user-shell to preseed the user shell
In some cases it is useful to be able to configure the user shell via
the installer. Especially when building live-images to deliver to users.
Add a new optional db_get passwd/user-shell and pass it to
adduser/useradd --shell/-s if it is set.
