The config_lkcd function in /sbin/lkcd checks to make sure things are sane,
then it sets the panic_timeout, and finally calls /sbin/lkcd_config. I've
not looked to deeply at /sbin/lkcd_config, but my guess/belief is that it
just issues ioctls against /dev/dump to inform the kernel where to dump,
etc
Looking at the "/sbin/lkcd save" side of things, I don't think any of the
'config' side steps are a prereq. This is further evidenced by the fact
that on my system, I do the save first, and have been successfully
collecting dumps.
So, I think my question still stands... Which one is supposed to happen
first?.. And once we decide, we need to either fix the rc.sysinit scripts,
and/or fix the README.lkcd.

p.s. I hope I'm not bothering people with these'details'. My goal, is to
have lkcd easily installable by end-users. Confusion in the documentation
will ( I feel) cause users to shy away.

Subject: RE: Which first? config or save
I'm not aware of any dependencies in lcrash itself on the configuration
parameters set by "/sbin/lkcd config". However, doesn't "/sbin/lkcd
save" rely on some values set by the config step? Perhaps I missed
something in the /sbin/lkcd script processing.
