Indeed.

The blurb should be modified as follows:

"Most development boards and devices have one or more LEDs. It is
useful during debugging if they can be wired to show different
behaviours such as disk or cpu activity or a load-average dependent
heartbeat. Enable panic and disk activity triggers so they can be tied
to LED activity during debugging as well."

If this blurb works, I'll send out another version.
