It is apparently related to sandboxing, namely to using namespaces (You need kernel support for it to reproduce. See about:sandbox in chromium.) I would really like to know what crazy is chromium doing to global system. Despite I like the idea of sandboxing I have to ask why it is part of "browser" and not some separate package. What's next? Bundled kernel? :) Also installing setuid /usr/lib64/chromium/chromium-sandbox ... Not even man page for it. Sigh... Milan
