Autogl preserve flag doesn't preserve

[damianharouff]

On the current iteration of autogl, the --preserve flag doesn't seem to be evaluated in the script, with the result that preserve doesn't.

Starting docker containers, from a previous iteration of the script:

Pulling and running current version of script with --preserve flag:

The script asks me if I want to delete everything. Typing n here will still result in everything being deleted:

The notice about using the preserve flag after responding n here will not be seen, because the screen is cleared moments later:

There is a log entry that we're preserving the existing docker environment:

The rest of the install proceeds as expected for the script. Once complete, my previous Docker containers are missing, and replaced with a fresh install:

Near as I can tell, the $PRESERVE variable is never evaluated in the script, other than for logging that it was set:
