honestly these have stumped me. i find nothing remotely resembling anything
that would cause a delay.. i have a hard time reading all the greek in these
things as many of these scripts make extensive use of regx.. i traced various
scripts they call/use all the way through and could find nothing even
remotely resembling a delay. guess ill have to try creating a script calling
iproute2 directly for addr assignments and see if it still delays, and if so
ill have to dig into the iproute2 code to see why. i really dont need these
delays in my work as debugging this behavior is making me fall severely
behind, but this boot problem is intolerable.

i never noticed it before now because i didnt have to reboot the old machine
in the past year, and updates have been done and just sit there for when it
does get rebooted. since this is a new machine i'm working on now, it was
quite noticable first time out.

or insecure system troubles and slowness or pay through the nose
