When trying to hit my new ITRS install, I get:

Software error:

at /var/www/otrs/Kernel/Config/Defaults.pm line 1803.

Looking at my Apache error log shows:

ERROR: /opt/otrs/RELEASE does not exist! This file is needed by central system parts of OTRS, the system will not work without this file.

[Wed Dec 06 09:26:10 2006] [error] at /var/www/otrs/Kernel/Config/Defaults.pm line 1803.\n

However, my OTRS install is stored in /var/www/otrs, not /opt/otrs.

Looking at Defaults.pm shows the {Home} variable - this is clearly the issue; {Home} is set to be /opt.

My question is: where does the {Home} value get set?
