Quite clearly SCO, Sun, and IBM have been doing this for years without
offering dozens of options. I don't need it to sing and dance, I just need
a way to put the dump where I can find it. I'm not going to put another
box in at the end of a serial or parallel port, I don't have NVram, I do
have lopts of disk, and so does almost everyone else. I have remote
systems in wiring closets all over the country (all four time zones). They
are at the end of open net connections, unreliable and untrusted. I don't
want to bet that I have a working VPN, or that I can safely send all that
data without it being read by someone other than me.
The AIX support has a group just to beat on dumps customers send. What
more evidence is needed that people can and do use the capability.
I had hoped that someone would do this for Linux, I never dreamed that
it would be kept out of the kernel by people who clearly don't understand
the problems if distributed and clustered headless systems.
I guess the development folks are working on more important things like
xiafs and morse code dumps to the keyboard LEDs.
