Hello,
1. Create a new user: `adduser test`
2. `sudo su test` and ensure that home directory is completely empty
3. `echo PS1=badprompt > .bash_profile
4. Switch back to main user
5. Start emacs with emacs -q
6. C-x C-f /ssh:test@localhost:
Expected result: dired for test user home dir.
Actual result: tramp hangs.
This kind of issue is well documented on the internet (stackexchange,
etc.) but I haven't seen a bug for it.
As I understand it, because `tramp-default-remote-shell' is set to
/bin/sh, tramp should ignore `.bash_profile`. When I look at running
shells, all I see is /bin/sh, so it's not clear to me where/why/how
/bin/bash is being invoked.
Thank you!
best, Erik Hetzner

Done. Just being curious: Did you test the "sshx" method?

Appreciated. Tramp 2.5.1 is scheduled for release end of June, if your
patch arrives next days, I'll integrate it. But there's no rush, I could
integrate it also anytime later.
