How about something without a pun or clever hidden meaning for a change?
Also no cute animal mascots, get a proper abstract logo.

OpenS-USE (Abbreviation from Open Source - Use)

This is my analysis of the situation: The name OpenSUSE is bad marketing and does need to change. I remember when I was choosing my distro the name was downright off-putting and made me initially overlook it as an option. It does not do OpenSUSE any favors.

The mascot and logo are very good, however. It is a solid design. Easily recognizable, somewhat cute and friendly looking. I even made it my app launcher menu button because I liked it so much.

The problem is that it is very difficult to base marketable name based on a chameleon. “ChamOS” or “Linux Cham” (pronounced “Kam” ), seems like a logical choice. However, people would just pronounce it “sham”, which isn’t making it any favors. You would have to drop the “H”.

Ultimately, the name has to follow the conventions of other distros. Such as “linux X” or “X OS”, where X is an easily pronounceable name with preferably fewer syllables.

My suggestion for names that would relate to the logo :

• CamOS (already suggested by someone else)
• Linux Green

Sussy

OpenSauce

• ChameLinux
• ChameleOS
• OpenCamo
• OpenChamo

Or, taking SUSE -> Soße -> sauce

• SauceOS
• OpenSauce
• SaucyOS
