These days I was working on a mini redhat9 customized installation. I deleted many rpms that I don't want and modified the comps.xml, and the whole dist can fin in just one cd. But at first I was trapped in this error: /usr/lib/anaconda/harddrive.py line 218 TypeError: in readHeaders an integer is required. Today I know the reason of the error. I stripped the dist to fit in one cd and I didn't use splitdistro and I didn't use genhdlist --withnumbers --fileorder pkgorder.txt [cddir1] [cddir2] ... the hdlist* in my iso was generated just by genhdlist /work/onecd/i386 and there isn't any disc seperation info in it, so anaconda errors. I used splitdistro and genhdlist --withnumbers --fileorder pkgorder.txt [cddir1] [cddir2] ... the hdlist* and mkiso and use harddirve install method Everything is now OK. X.H.
