I’ve tried to change the default Linux console on Fedora Silverblue (30) with the usual
chsh, but that was not even installed! I also could not find any package to install via
rpm-ostree or so.
So how can I change the default login shell on Fedora Silverblue?
potential workarounds that allow to change the login shell of any other user, but IMHO, this is no really clean solution.
So why is not
chsh available on Silverblue?
util-linux-user to get
[returntrip@silverblue30 ~]$ toolbox run dnf provides chsh

Okay, funny, I need to get used to that
dnf provides command as it seems…
However, the question is if it is worth to layer this small Linux utility just to change your shell. (After all, you usually only do so once.) And layering involves a restart etc. Just to change your shell, this could be a little too much. (Even… or especially, if you then uninstall it afterwards.)
The question is, does it do something more than just edit
/etc/passwd? If not, then I can also edit that manually.
Or e.g. run preinstalled
usermod like this, as I now did:
usermod -s /bin/bash $USERNAME
Not sure if it changes anything more than
usermod --shell <shell> <user> but I guess it does not.

this thread @refi64 actually presented the “real” Silverblue solution:
Fedora intentionally doesn’t include chsh because it’s setuid root which is a bit of a security rabbit hole, use
sudo lchsh $USER .
I’ve tested it and it works flawlessly!

@refi64’s solution does not seem to work anymore even
sudo lchsh does not work anymore in recent Silverblue (Fedora Silverblue 33):
$ sudo chsh $USER
sudo: chsh: command not found
This previously mentioned
usermod command does work though:
$ sudo usermod -s /bin/bash $USERNAME
