Re: [Freeipmi-devel] segfault in ipmi-chassis

[Albert Chu]

Hey Rob,

Thanks for the catch.  The OPTION_ARGS_OPTIONAL flag is set in the
argument parsing logic above, which appears to be a cut & paste legacy
error from years ago.

--set-boot-flags and many other options in ipmi-chassis were legacy'd
out a long time ago, but the code was left there for backwards
compatibility. The preferred tool became ipmi-chassis-config (which all
config tools are now collapsed into a single 'ipmi-config') for setting
those parameters.  So that's why there is no help output/manpage info on
them.

I imagine you were trying the options b/c you were looking through code?
I'll add some comments that things are legacied out.
