Thanks for confirmation! So there's no problem with Tramp. I'm closing

[Message part 3 (message/rfc822, inline)]
Hello,
I'm having a problem opening files as root.
From emacs -Q, I issue
`(require 'tramp)`, customize tramp-verbose to 10, and try to open a
file as root: `C-x C-f /su::/etc/fstab`. I'm then prompted for my root
password. Entering the password, Emacs pauses for ca. 10 seconds, then
appears to open a new file called fstab, but it's not the fstab that
already exists in /etc/fstab. The message about calling make-directory
to create the parent directories shows up, so I've apparently opened a
new file somewhere. I can't see where, exactly, as `C-x C-f`, or even
`M-x shell-commmand pwd` both prompt me for the root password, and then
fail.
Despite having turned `tramp-verbose` to the maximum value, there's not
much in my *Messages* buffer after all this:

This is all on a laptop, I'm not trying to connect to another machine.
