This is great information; thanks for providing it! I found it quite
educational/informational. The documentation Antony provided seems to
indicate two things:
1) That savecore(8) should really be run before swapon(8) -- I don't see
any indication that swap needs to be made available prior to mounting
filesystems, which is what Doug B. was stating was a necessity.
2) That even regardless of Item #1, savecore(8) should be working
(assuming that kernel dumps are still written from the end of the swap
device to the front (e.g. backwards)), and that swapon(8) shouldn't be
stomping on kernel dumps.
I haven't tried changing the rcorder of the /etc/rc.d scripts in
question to see if it works. My gut feeling says it probably will, but
I'm not sure of the implications.
Doug, can you provide some comments/insight here when time permits?
