Linux players bond for business software (News.com)

All of the distributors involved in United Linux are involved in the LSB effort, as are Debian, Mandrake, and Red Hat.

IMHO United Linux is more an effort to pool resources on maintaining core packages than an effort to provide a common distro. It only makes sense for everyone who's using RPM format packages to do that; otherwise, it's duplicated effort. The trick is to do it in a way that doesn't hurt building on the core.
