Using "-" to get it to dump the secroots output to stdout is a new
feature added for 9.11.  That hasn't been published yet, but if you build
from the source tree at source.isc.org (like Tony does), you can it.

If you're doing that, then you can *also* use "rndc managed-keys", which
lets you check key status and force keys to be refreshed ahead of schedule.
