Reiser4 support on parted ...
Hi Everyone, I am looking to know if someone have time to share with me to add the necessary code inside 'parted' to support Reiser4. May be 1 or 2 hours per day. The reference page is: http://www.gnu.org/software/parted/#maillist I start to work on it, last September. Of course no money is involved. I will need also other people, to test the result. Thanks, Giovanni. -- -- -- Check FT Websites ... http://www.futuretg.com - ftp://ftp.futuretg.com http://www.FTLinuxCourse.com http://www.FTLinuxCourse.com/Certification http://www.RPMParadaise.org http://www.YourPersonalOperatingSystem.com Mobile: +39 393 665 4239 Lancelot is back! --
