The ipmi-console command can be executed by any normal user and doesn't
require "system administrator" (aka "root") permission., IMHO, it should
hence be installed to /usr/bin, and not to /usr/sbin., The fact that you
are accessing an IPMO SoL console of another machine, (of which you may
be the system administrator) doesn't mean you have to be the system
administrator of the client running ipmi-console.

Debian FHS 3.0 states:

This implies that not only the "other" commands but also the utilities
for system-administration are "root-only" - which in the case of
ipmi-console they clearly are not.

I'm not familiar enough with other parts of freeipmi-tools, there
might be more commands that share a similar situation.
