+If you want to run as root you may have to set

+: /etc/my.cnf
+: [mysqld]
+: user=root
+
+To check error output in a file on start-up run with something like
+
+: mysqld -u mysql --console --explicit_defaults_for_timestamp --datadir=/gnu/mysql --log-error=~/test.log
+
+Other tips are that Guix installs mysqld in your profile, so this may work
+
+: /home/user/.guix-profile/bin/mysqld -u mysql --explicit_defaults_for_timestamp --datadir=/gnu/mysql

+When you get errors like:
+
+: qlalchemy.exc.IntegrityError: (_mysql_exceptions.IntegrityError) (1215, 'Cannot add foreign key constraint')
+
