I've painted myself into a corner:
My machines each have only sudo user which is local to the machine. I setup an autofs to mount over top of /home; the mount does not include a folder for the sudo user.
I can't log in to the machines to change the sudo user's home directory, nor add a different user (who does have a /home directory to the sudo group).
Is there any way to execute a command over ssh without having a home directory. Alternatively, I can log in as a non sudo user, so is it possible to execute a command using su without a home directory?
