[Yum] yum repolist vs. grep -i enabled *.repo

[Larry Vaden]

Hello,

After attempting a migration from CentOS 5.5 to Scientific Linux 5.5,
the result is a system in an inconsistent state.

The basic stanza used for the migration was from
SCIENTIFIC-LINUX-USERS at LISTSERV.FNAL.GOV and is below the yum/grep
output.

Trying to learn more about yum and its use, I ran the commands below the sig.

1) What am I missing about the possible/perceived discrepancies
between the outputs of yum repolist and grep?

2) For a given installed package, is it possible to get yum to
identify which repository was used for the installation?

THANKS for your thoughts.

kind regards/ldv

"To be REALLY sure of a full conversion one might try:

yum reinstall $(rpm -qa --qf "%{name}.%{arch} %{vendor} \n" | \
 grep -i centos | cut -d ' ' -f 1 | sort | uniq | grep -v kernel)

Need special handling for kernel and kernel-devel as you will get
messages about multiple versions being allowed, and cutting off the limb
on which you are standing is not recommended."
