Yikes! Something strange in a cron job.

To clarify the command is "mysqldump dbname"
I didn't specify a user because my understanding is that whatever system
user (in this case root) and password doesn't need to be specified as long
as long as the .my.cnf file is resident in their home directory and
contains the correct credentials that the system user wants to be against
This works perfectly when I'm logged in as root, but for some reason
mysqldump doesn't want to read the my.cnf file from from /root when run in
This makes me wonder if I need to specify HOME as in "export HOME=/root"
I'm going to give that a shot and see if it solves the problem.
