When purging the server package, the user should be given the option to remove data files. This is especially important if switching between MySQL and MariaDB, as they are not compatible, so not cleaning up after one is likely to make installation of the other fail.

However, the dialogue for this is never shown.

The cause is that there's a check that skips the dialog if the server binary exists (is executable), which never passes. It seems to have been copied from an old version (4.1) that had the logic in the metapackage mysql-server (Debian bug #307473).

Checking the file shouldn't be needed any longer.
