The ability to collect logs during the installation (diskful and diskless) can be enabled by setting the "site.xcatdebugmode" to different levels (0,1,2), which is quite helpful when debugging installation problems.
The logs during diskful provision:
The diskful provision logs:

* Pre-Install logs: the logs of pre-installation scripts, the pre-installation scripts include "%pre" section in anaconda, "<pre-scripts/>" section for SUSE and "partman/early_command" and "preseed/early_command" sections for ubuntu. The logs include the STDOUT and STDERR of the scripts as well as the debug trace output of bash scripts with "set -x"
* Installer logs: the logs from the os installer itself, i.e, the logs of installation program (anaconda, autoyast and preseed,etc.)
* Post-Install logs: the logs of post-installation scripts, the post-installation scripts include "%post" section in anaconda, "<chroot-scripts/>" and "<post-scripts/>" sections for SUSE and "preseed/late_command" section for ubuntu. The logs include the STDOUT and STDERR of the scripts as well as the debug trace output of bash scripts with "set -x"
* PostBootScript logs: the logs during the post boot scripts execution, which are specified in "postbootscripts" attribute of node and osimage definition and run during the 1st reboot after installation.
