It is more likely that it is a problem with the mysql sysvinit script
and mysqld itself. What is probably wrong is that mysqld is daemonizing
and returning control to the terminal before it is _actually_ ready.

Note that in Ubuntu the upstart job for mysqld runs it in the foreground,
and the post-start _polls mysqld_ so that anything that wants to be
'start on started mysqld' will have a working mysqld.

Still, I would appreciate the "it doesn't work" full description too.
