Right, we will not catch errors if we do not test packages. It was a
problem within old MySQL /Sun/Oracle, as packages were produced after all
development was done , and buildteam black magic was required to do it.
But here, we can produce/test packages per-push or nightly, to avoid
The number of parameters is kept to minimum, and those are unlikely to
disappear (sql_mode, default_storage_engine, innodb_buffer_pool_size,

There is a problem with .cnfs, they do not scale with RAM. Also, Arjen
wants to get the number of example .cnf down to 1, with hardcoded values and
also make it Unix (with O_DIRECTS , paths with /usr and what else).
Maintaining a copy "master" my-example.cnf for Windows, and selectively
applying changes to my-example.ini, is not something I'm very keen on
Currently, I'm trying to avoid a situation, where people install Oracle's
MySQL with all defaults, try it out, then install MariaDB with all defaults,
try it out, and find out that ours sucks in comparison performance-wise, or
their application would not work as expected due to some weirdness in

I tried ConfigWizard yesterday, they have "standard" (one click) and
"detailed" (many clicks). So I took "standard" as label. "Optimized for
transactions" sounds also fine with me.

Will ask him.
