Beg pardon? Why are you caricaturing what I said? I don't believe any of
us who are complaining are talking about every small change; rather, the
major ones.

As a lesser example, I just *adore* the new ethernet names - NOT. Breaks
scripts, makes it all more difficult, not to mention *so* much easier to
guess, when you've debugging a box and your organization has hardware from
many OEMs. What was wrong with eth0, or even em1? Why go to Sun naming
conventions? Maybe it helps EEs, but not sysadmins.

Please, though, that naming is *not* the point of the thread.

Why not what was suggested, a summary every month or three? How about
sending announcements?

Which a vast number of us strongly opposed, but were not listened to. That
stuff is fine for a desktop, but who *cares* How Fast a *server* Shuts
Down? And coming up - hell, damn HP server take for-bloody-*ever* with
their firmware, init V is faster than their firmware.

May be, but my federal agency is at *least* 5% under what we were getting
in 2003, and my manager, who's working with another Institute about 2/3rds
of his time, and I, and another admin have to manage over 170 servers,
workstations, and clusters, some with special software, and ranging in age
from just bought to 2007 (I think there may be a workstation or 3 older),
and some of which we haven't managed to get the owners to allow us to get
off CentOS 5....

And I ask permission from my fed manager to put in a ticket with upstream
(which reminds me, I need to ask about putting one in for those docs with
links to google ads).

Lack of time, as I've indicated.

Oh, I remember when you couldn't be sure, pre-NM, what would be eth0,
until you put the MAC address in....
