This rewrites the name of the errata so you don't get conflicting
errata names essentially you cant have two erratas with the same name
even if they are on different channels.
for example RHBA-2012:1441 would be published in spacewalk as
CENTOSX86_64BA-2012:1441

these flags deal with alternate package names in Centos here is an
example in the Redhat errata it might say the package is names
at-spi-1.28.1-2.el6..x86_64.rpm but the Centos 6 name for the package
is at-spi-1.28.1-2.el6.centos.x86_64.rpm this happens when Centos has
added an additional patch that wasn't in the Redhat version of the
rpm.
These flags make it match the right package in the channel if it
matches the el6 or el6.centos
you should always use this for Centos channels

this would give you better results
./eva-direct-errata-sync.pl --sourcechannel=rhel-x86_64-server-5
--destinationchannel=centos5-x64-base-channel
--rewritepackagereleasefrom el5 --rewritepackagereleaseto el5.centos
-F day  -e RH  -E CENTOS5X64

./eva-direct-errata-sync.pl --sourcechannel=rhel-x86_64-server-6
--destinationchannel=centos6-x64-base-channel
--rewritepackagereleasefrom el6 --rewritepackagereleaseto el6.centos
-F day  -e RH  -E CENTOS6X64

./eva-direct-errata-sync.pl --sourcechannel=rhel-i386-server-5
--destinationchannel=centos5-x32-base-channel
--rewritepackagereleasefrom el5 --rewritepackagereleaseto el5.centos
-F day -e RH  -E CENTOS5X32

you were very close

one piece of advice I posted a new version of the script yesterday
that fixed a few long standing bugs so make sure you have the latest
version
also I intend to release a new version latter this week to handle
multiple target base channels which should reduce the need to rewrite
the errata names.
