Subject: Eliminate the guesswork when attempting to determine the id of a
X-Git-Url: https://git.entuzijast.net/?a=commitdiff_plain;h=a653740fefe24edefe7fc3aaf84b14655778c5be;p=imunes.git

Eliminate the guesswork when attempting to determine the id of a
newly created ng_eiface or ng_iface node.  The replacement
approach at "ngctl mkpeer" invocation yields deterministic
results, and reduces the spawned process pipeline at the same time,
thus reducing the time / CPU cycles wasted on ng node creation.
