Why would anyone want the GPLed source code in MEPIS?
A2. Except for a few packages, the sources are available at the Ubuntu and Debian repositories. The MEPIS kernel source is available from the MEPIS repository. So there is no obvious reason for anyone to want to get the MEPIS related GPLed source code from MEPIS, except to verify that MEPIS is complying with the GPL license restrictions.
