Subject: Direct output from fail() to stderr
X-Git-Tag: 1.13~6
X-Git-Url: http://git.annexia.org/?p=virt-what.git;a=commitdiff_plain;h=2f47e0615dab2bb16c2ad1e9f1273b3b709aea54

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.
