There is no editor. As IncusOS has no local shell or SSH support, all interactions with it must be done over the API, so in this case, you’d use incus remote add on your host to add the IncusOS server, then use it as a remote, which will then use your local text editor.
Using incus exec against IncusOS is only there for development/debugging and isn’t part of normal use of IncusOS (and will be removed soon).
Hello @el_dep,
I changed the default editor used by Incus client like other linux / unix shell by create environment variable EDITOR. I my case, I added “export EDITOR = vim” in my ~/.bashrc to set “vim” editor used in my shell with command CLI Incus or IncusOS, example “incus admin os network edit” to edit network configuration of IncusOS server. All questions are good !
