Although it is not my decision, I think the "polite" thing to do would be to leave the CentOS trademarks out, but give adequate and glowing credit to the CentOS developers that made the OS possible.
Hi,
I work at Wincor Nixdorf, and we want to provide a distribution derived from CentOS as commercial product. Within the distribution we provide software for installing, configuring and operating our "Beetle" POS systems with regard to our customers' needs. The name of the distribution is "WNLPOS", which means "Wincor Nixdorf Linux for Point of Service".
Our actual version of WNLPOS is based on Fedora Core 4. There we eliminated "Fedora" out of menues and artwork, and we created an own artwork just with "WNLPOS" as name.
The question now is if we may mention CentOS in the derived distribution at all. This concerns for example the name of the grub menu entries, and the splash screens and wallpapers of Gnome and KDE. Are we allowed to write "WNLPOS - based on CentOS"? May we use the original logos (artwork), or is it allowed to modifiy them?
