Did my half-yearly upgrade (which went smooth for once, just the usual clearing old containers because of disc space)…
But at the beginning I saw some message about app.yml being far too visible (app.yml visible worldwide) and a command to fix it with.
Of course upgrading is long enough to scroll that message past any buffers and google is your friend (or the search here) isn’t helpful this time. Trying to guess which log file the info might be in… uhum.
Pretty certain someone here says tada in about two seconds though but in the end I just run the thing again to see the message even if the forum is down for another few minutes. So for reference:
chmod o-rwx containers/app.yml
And as an improvement I really would love to see in *nix logging… any processing that takes several pages should always END with a message saying (the operation performed was logged into xxxx.log).
