Let me clarify myself here - the boot block itself may not always process any arguments passed to it from the OBP 'boot' command. In the case of the -Z flag, I'm sure it does because it needs to start executing the kernel from the right BE. But it also passed these flags on to the kernel its booting, so that the kernel knows it. That's how a 'boot -s' from the OBP eventually manifests in init(1) knowing that you desire single-user mode, and in this case the chosen BE, and so on. /dale _______________________________________________ sysadmin-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
