Created attachment 542218 [details] env-update error output This is an extremely minor issue, and frankly I'm probably being nit-picky about this, but env-update should politely remind the user that it needs to be run as root. Currently, running it as a non-root user spits out the attached log. (Yes, I actually ran it as a non-root user, completely forgetting that it needs to be run as root, hence my noticing this.)
We also support unprivileged modes, so we Could do something like this to check if the relevant EROOT is writable: os.access(first_existing(EROOT), os.W_OK))
