Comment 4 for bug 490265

The /var/log/syslog file

On newer systems (6.10 and up) this is often the most important file and should be attached to crash reports.

After installation, this is saved as /var/log/installer/syslog.

The /var/log/partman file

If the installer crashes at or beyond the partition stage (the re-organizing of your hard disk), then this file is also likely to be important.

After installation, this is saved as /var/log/installer/partman.
