Subject: Direct output from fail() to stderr
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=529a4ee39442c3f254955e036b8e5172d15e7be1;hp=529a4ee39442c3f254955e036b8e5172d15e7be1;p=virt-what.git

Direct output from fail() to stderr

This allows callers to more easily differentiate valid output from
errors.  A recent example is facter.  When calling virt-what for its
virtual fact, it gets 'virt-what: this script must be run as root' as
the fact value when run as non-root:

$ facter | grep ^virtual
virtual => virt-what: this script must be run as root

This is mildly related to RHBZ #719611¹.
