Can apply to upgrades from MySQL <= 5.7 too.

Some postinst script that detects config settings that write to /home and others (includes MDEV-10399)

  • datadir=/home/* -> and disabled ProtectHome

and drop like adding an extra file like:

Consider ProtectSystem directories, probably with a warning.

MDEV-25177 improves the error message to hopefully be able to determine the cause a bit better.
