It will even be incorrect on many Linux distributions (Ubuntu for
example), many of which default to /etc/mysql/ instead of /etc/.

"It depends." As a rule, MySQL clients *do* read $sysconfigdir/my.cnf
and ${HOME}/.my.cnf by default, if they exist. But when you have MySQL
packages and MySQL clients built with conflicting ideas of where
$sysconfigdir should be, things start to fall apart. This problem is
going to exist anywhere except an Apple-like walled garden.
There exists a Linux Filesystem Standard that lays out in general terms
what should be expected to be where. There are many distributions that
follow it. There are also many that don't. And then you get into *BSD,
and Solaris, and...
