If someone is new to PE, trying out a split install, and then using the simplified agent installer, we could be slightly more clear about the URL they need to CURL against in this section:
We say: "The script can be found at https://<master hostname>:8140/packages/current/install.bash" and leave it up to the user to fill in the value for <master hostname>.
This needs to be the compile master itself, but it's possible that a new user will be thinking of the console as "the master" - our terminology thus far has been about considering these to be the same thing.
A very simple fix for this would be to add a quick helpful parenthetical, such as:
(remember, in a split install, this url will be of the master, not the DB or the console machines)
Note that the Node Requests page in the console shows this URL exactly as it needs to be, so users having seen that will have seen the right URL. But users relying more on the docs may run into this small vagueness and get slowed down.
