MEPIS LLC, a longtime Debian Linux distributor, is switching from Debian to Ubuntu as the basis for its SimplyMEPIS Linux distribution.
In the past, MEPIS was one of the leading lights of the DCC Alliance, a group of nonprofit and business organizations that had been working on producing a Debian-based core Linux distribution that would also be LSB (Linux Standard Base) 3 compliant. However, MEPIS has now parted from the DCC Alliance.
MEPIS is no longer involved with the DCC due to creative differences. We wish Progeny, Xandros, and Linspire the best of luck in their mutual endeavors, said Woodford.
