Johnny, or any one to answer. http://www.linuxhelp.net/forums/How_to_Build_Enterprise_Srpms_t3384.html As it seems this was done in 2004. Is there an updated version to it? Also the required pckages needed. I have the info from WBL site and various scripts from the centos site. What i am really interested in is the main os rebuild with anaconda runtime. I'm not after creating a live image. Great article. -- ~/john OpenPGP Sig:BA91F079
