Was hoping to leave this enabled for a little while as core community
members test this script out, but Apple's aggressive release timeline
for macOS 15 Sequoia has caught us off-guard here.
It's probably not ideal for a general audience if the script spews all
of this output--and people can still force bash to run in trace mode
if we really need to debug a problem.
While we don't have any easy way to forcibly notify everyone about the
impending breakage (or forcibly migrate the users on their system),
this script enables those who do hear about the problem to migrate
their systems before they take the macOS update.
It should also enable people who only discover it after the update
when a build fails to ~fix their installs without a full reinstall.
