I have created a plist for MySQL that should start on demand on PowerMac G5
using Mac OS 10.5.7.  However, when I look at the process list, I'm seeing
the following:

  116   ??  S      0:00.04 /bin/sh ./bin/mysqld_safe
--datadir=/usr/local/mysql/data
--pid-file=/usr/local/mysql/data/darnoc-desktop.local.pid
  143   ??  S      0:01.61 /usr/local/mysql/bin/mysqld
--basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
--pid-file=/usr/local/mysql/data/darnoc-desktop.local.pid

Note:  After rebooting the machine, I'm seeing the following:

sudo launchctl list | grep mysql

143 - 0x10c5d0.mysqld
143 - 0x10b430.mysqld

Now, when I perform the following on MacBook Pro:

sudo launchctl unload -w
/opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist

sudo launchctl list | grep mysql

<no results>

sudo launchctl load -w
/opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist

sudo launchctl list | grep mysql

232 - 0x100119dc0.anonymous.mysqld
202 - org.macports.mysql5

Would it be possible to put job in a bad state if you edit its plist file
while it's loaded?  At this time, I
can connect to the MySQL process without getting a connection error even
when the job is loaded.
