[lxc-users] Snap 2.20 - Default Text Editor

[Stéphane Graber]

Because of the way the snap works, it doesn't actually have access to
your system's filesystem and so can't run commands from your system.

Only binaries that are part of the snap or the minimal copy of Ubuntu
that the snap uses can be used by it.

We ship a copy of vi in our snap to make the editor function work,
that's why you get vi regardless of what EDITOR/VISUAL points to in your
environment.


You can workaround this by using something like:

    lxc config show NAME > out.yaml
    <favorite editor> out.yaml
    lxc config edit NAME < out.yaml

The same is possible for all the other objects which come with an "edit"
command.
