Re: komd issues - was [Re: [openMosix-general] openmosix 2.4.26 in 2.4.31?]

If it's testing that's not a problem. I am going to start testing tomorrow
when I finish the stuff I am currently working on. 

As to what concerns the re-write, that's just a side project and that will
require more work. Since it's so different from openMosix I may actually
wait for 2.8 to release it.

possible (and integrate it in the main git distribution), more people

Do you mean we should not work on the current git anymore ?? and will kcomd
integrate this new code as well ?
