As a former summer employee of ORINS and ORNL during my college years
in the 60s (and therefore somewhat biased) and now a rural ISP with
all the dependencies that implies regarding support from the greater
Internet community, I agree with Christopher and Bart about the
justification for moving from CentOS to SL.

So, today I used Phil's stanza and wound up with the results below the si
g.  

The list below the sig was truncated (right or wrong) by, e.g.,

rpm --Uvh --force
http://ftp2.scientificlinux.org/linux/scientific/55/i386/SL/basesystem-8.
0-
5.1.1.noarch.rpm

However, the following remain:

[root@shell work-2011-01-25-migrate-centos55-to-scientific-linux55]# yum
list installed | grep -i centos
geronimo-specs.i386                     1.0-0.M2.2jpp.12.el5.centos

installed
[root@shell work-2011-01-25-migrate-centos55-to-scientific-linux55]#

Further, 'rpm -ivh' using the SL kernel rpms fails with messages like

[root@shell SL-rpms]# rpm -ivh kernel*
warning: kernel-2.6.18-194.32.1.el5.i686.rpm: Header V3 DSA signature:

What did I do wrong and/or how do I fix this?

Returning to Phil's comments, how do I know when and whether the migratio
n 
was complete and correct?

It is not a production system, just a beach front from which I work.

kind regards/ldv
