Upgrade packages are ready for SimplyMEPIS users. They are binary compatible with Debian, so others can also use them.
“The pool is meant for users of the 3.4 release and pre-releases of SimplyMEPIS. The upgrades may also work for earlier versions of SimplyMEPIS”
Desktoplinux has an article about the content of the updates and that Debian users also can use them.
MEPIS creator Warren Woodford said, “For this release, MEPIS and Debian kernels are binary compatible if the kernel version and flavor are the same. Users of Debian kernels are welcome to use the MEPIS pre-built drivers.”
