distributions and compatibility

[Tim Callaghan]

I have a question regarding the "supported" platforms of an
application.  I'm looking to install Infobright's Community Edition
(ICE), which their site states is compatible with the following 64 bit
distributions:
1. Red Hat Enterprise Linux 5
2. Debian 'Lenny'
3. CentOS 5.2

I'm currently running a 64 bit Fedora 9 machine and just installed
Oracle 11g on the machine.  Prior to the install I needed to change
/etc/red-hat-release to "redhat release 5" so the installer would
continue past the OS check.

My question is what, if anything, should I be concerned about to
install ICE.  Is it just something I should try and see what happens?
Are there major differences between their supported platforms and
fedora 9?

TIA.
