required kernel rebuilds

[Michael W. Lucas]

Hi,

Book research question.

Way back in the Dark Ages of the 1990s, it wasn't uncommon to rebuild
a kernel to fix a recurring panic. You'd have to tune MAXUSERS, or
PMAP_SHPGPERPROC.

AFAIK, dang near everything is tunable in either loader.conf or
sysctl.conf. I really want to say that kernel rebuilds for these kinds
of limits aren't needed any more.

Does anyone have a counter-example, though? Is anything possibly
crash-inducing non-tunable without a kernel rebuild?

Thanks,
==ml
