Hi,

yes I know and used manageBE for a while, I even mentioned it
in the HOWTO (quote below) but thought that making *beadm*
that is compatible with Illumos/Solaris version would be nice
idea, *beadm* is also more comfortable to use, at least for me.

Mine *beadm* has also a feature to activate BE's from other
machines.
