hi, comps in rh9 is comps-9-0.20030313 while in the latest centos-3.4 it's comps-3.4centos.0-0.20050105 so the rh9 has higher version number which means this packages not upgraded during an upgrade to any version of centos. and yum also not upgrade this package. imho it's a bug. is there any way to find out what other packages is remain from some older rh version? yours. -- Levente "Si vis pacem para bellum!"
