Thanks all for the replies.
Oddly, there is no mysqld/ directory in said location. This confuses me as well. There is also no instance of mysqld running. It looks, in fact, very much as if it were never installed--since there is also no mysql startup script in init.d--except that the mysqld executable obviously exists (per the output shown in the OP).
Also, I've looked into many howto's on installing mysql on Ubu-srv 9.10, and all were business as usual, so I'm led to believe that there are no selinux-like issues, but have been wondering the same thing (about port/service blocking).
<grumble onread=ignore>What I find so frustrating about this sort of thing is what I find frustrating about a great many things Linux--I haven't the faintest notion where to begin looking. Often, simply tailing the syslog leaves me no clues, and if a log file (or error log file, or...) even exists for the application, I'm left with the same. In this case, I've spent hours googling and poring over the documentation, troubleshooting, etc., and...ah, nevermind me...</grumble>
