Hi there! I'm using GuixSD 0.12.0 and ran `guix package --install=mysql` (which I gather gave me MariaDB 10.1.19), then created a database and tried to reload a database dump of a decent sized existing database: zcat dump.sql.gz | mysql DBNAME which failed with: ERROR 2006 (HY000) at line 2266: MySQL server has gone away Reloading the same dump works for me on default MySQL in Trisquel 7. The database dump was created on Debian with `mysqldump --no-create-db DBNAME`. On Guix, I was able to reload the dump by running mysqld with a custom config file with max_allowed_packet=16M under [mysqld]. It appears that the default value for `max_allowed_packet` under Debian/Trisquel is "16M", where under Guix it is "4M". The mysqldump defaults bunche a whole lot of records into a single insert statement for performance, which is why I'm getting a value > 4M. Could it be worth setting max_allowed_packet to 16M in Guix's `mysql-configuration-file` function for consistency with Debian? Regards, Ben
