Sure it's easier, but which is safer?
I don't have Charles first message on this topic, but I believe
his error message was from logrotate which is a cron job.
If Charles put
mysqladmin -uuser -ppassword
into a cron job, then the user's(root?) password would be in
open view to anybody who could view the crontab - granted, you
would have to be root to view the root crontab, but putting
the password to the MySQL user right in the cron command is
just a little too "loose" for me. A safer method would be to
"hide" the user/pw in the Unix user's home directory in the
.my.cnf file, as I outlined below.
