Doc Text:
Previously, the /usr/libexec/ovirt-config-boot script reported errors to standard output. However, this made it difficult for an application that called this script to detect these errors. To resolve this issue, the underlying source code has been updated to write all error messages to standard error.

Description Doron Fediuck 2010-11-29 12:08:51 UTC 
Description of problem:
When an error occurs, /usr/libexec/ovirt-config-boot logs the error
to stdout, and other programs calling this script fail to get the error.

How reproducible:
Try to upgrade to rhel 6, just as a way to get an error.

Steps to Reproduce:
(taken from mail:)
  Sun, 28 Nov 2010 11:00:50 DEBUG    ['/usr/libexec/ovirt-config-boot', '/var/vdsm/image-update']
Sun, 28 Nov 2010 11:00:50 DEBUG    installing the image.
cannot upgrade from 5.5-2.2 to 6.0.

Sun, 28 Nov 2010 11:00:50 DEBUG    
Sun, 28 Nov 2010 11:00:50 ERROR    <BSTRAP component='doUpgrade' status='FAIL' message=''/>

Expected results:
Once this is reported to stderr, the message will get the relevant text.

Additional info:
Relevant for future versions (6.0) as well.
