Document what scripts, etc get run for remote SSH sessions

System details:

Mac, Sequoia 15.5, sshing into a Debian GNU/Linux 11 (bullseye) x86_64

Describe the issue:

RemoteHost ssh does not run the .profile file when it connects to remote machine.

On the remote machine, there is a .profile file which is just the line

sudo su - new_user

when I run the command in the terminal

ssh -i ~/.ssh/... username@ip_address

then the file correctly runs .profile and I am the correct user at the repl.

When I do Remote-ssh: Connect to host in VS Code, it likewise works.

However when I do the same on Positron

When I do Remote-ssh: Connect to host and enter in my command

ssh -i ~/.ssh/... username@ip_address

then I am the original username, not the new one that the .profile switches to.

I think the cause might have something to do with the R version on my remote machine. For whatever reason, the R version on my remote machine is super old, R 4.0.4, a version unsupported by Positron.

My guess is that there is an error when trying to connect to an R instance, and this error happens before running .profile. Then it skips that command?

I am not sure how to get a more up-to-date version of R. when I use rig I get a 403 error... I guess I should talk to my system administrator.

Steps to reproduce the issue:

1. Install remote connection extension
2. Run the "setup remote connection" command
3. Input the ssh command

Expected or desired behavior:

Same behavior as VS Code

Start with the “setup remote connection” command and the reported SSH command, then compare Positron’s behavior with VS Code Remote-SSH. Document which scripts run during remote SSH sessions, including whether .profile is sourced, and verify the explanation against the reported Debian environment.
