Nagios just drops privileges. It doesn't handle parsing environment
variables already set by the user. And for all it knows, it could
be wrong if it tries to do so.

You could set whatever vars you want in /etc/sysconfig/nagios though
and have them work properly for every check Nagios runs. You can use
shell from there, so
HOME=~nagios
would be perfectly valid.

The /etc/sysconfig thing only works on reasonably recent versions of
Nagios btw, but setting the vars in the init-script would have much
the same effect.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
