dtrace discuss - Oct 2007 - anon tracing help

DTracers,

Do you know how to fix the failure in the last command ?

TIA,
Bhaskar



# dtrace -A -n ''BEGIN {trace(`kmem_flags); exit(0); }''
dtrace: saved anonymous enabling in /kernel/drv/dtrace.conf
dtrace: added forceload directives to /etc/system
dtrace: run update_drv(1M) or reboot to enable changes

# dtrace -n ''BEGIN {trace(cl_orb`__1cIorb_confMcurrent_node_.ndid); 
exit(0);}''

This does not seem possible as currently there is no runtime kernel
symbol relocation support in the dtrace (7D). More specifically,
dof sections of type DOF_SECT_KRELHDR needs to be handled for this
to work, imo.
