Unable to remove /su:user@host:/ part when using counsel-find-file from file opened as root

[ngleb]

Hi!
I'm recently switched to counsel and I have a strange issue with counsel-find-file. I often use Tramp mode to edit files as root via su:

1. Emacs is open at $HOME, so there's no Tramp in use. Press C-x C-f, prompt is ~/
2. Type //
3. Type su://
4. Enter password, then I get this prompt /su:user@host:/
5. Proceed with path to a file, e.g. /su:user@host:/etc/hosts and hit RET to open the file.
6. Now I need to open another file as a regular user. Press C-x C-f, now the prompt looks like this: /su:user@host:/etc/. And this is where problem begins: I cannot remove /su:user@host:/etc/ with Backspace or with //. Only pressing ~~ helps, but then I am at the $HOME.

Is this expected behaviour?

👍 to this, seeing same issue.

This is expected. The reasoning is that // brings you to the root of whatever host you are on right now.

• You can press / C-j to enter the root of localhost
• You can press ~~ to enter your home on localhost and then navigate to root.

Ideas on improvement are welcome, especially if we don't have to sacrifice the old functionality.

Maybe pressing /// can jump to the root of localhost? I feel like that would be intuitive enough for people who want to do this to discover it by accident.
