... which probably uses BDB so it's as easy to "corrupt" as sneezing :)
But yes, what I'd wish is that the default behaviour of all (shutdown,
reboot, halt) be as "shutdown" is now, and introducting a command line
switch (I see "-f" is not taken) for the odd emergency case when the
old behaviour is needed. I'd also advocate "halt" meaning "shutdown
-p", i.e. shutdown with poweroff instead of just stopping the kernel,
which is mostly useless.
