Looks like the screenlog.* is added by someone for screen tool.
I am curious whether the part of code you meantion in the dhclient-script has been executed. Looks like it depends on whether there is a log server is configured in the dhcpd.conf.
xCAT needs to take a look to make the syslog to be forwarded to MN.
Thanks
Best Regards

The screenlog line is added in the dhclient-script script of the genesis image :
(/opt/xcat/share/xcat/netboot/genesis/x86_64/fs/sbin/dhclient-script)
if [ ! -z "$new_log_servers" ]; then
head -n -1 /etc/rsyslog.conf > /etc/rsyslog.conf.new
cp /etc/rsyslog.conf.new /etc/rsyslog.conf
fi
for ls in $new_log_servers; do
echo *.* @$ls >> /etc/rsyslog.conf
done
I really don't know why the file is managed this way.

My current rsyslog.conf file is :
$ModLoad imuxsock
$ModLoad immark
$MarkMessagePeriod 1200
$ModLoad imfile
$InputFileName /screenlog.0
$InputFileTag screenlog:
$InputFileStateFile stat-screenlog
$InputRunFileMonitor
$InputFilePollInterval 2
*.emerg *
*.* @192.168.132.2
# keep the last comment line empty, because it is dynamically trimmed of
# at boot by dhclient-script
#
I'm not satisfied with hard-coding the ip address of the syslog server though...
The invalid line is still added by dhclient-script (where does the
new_syslog_servers variable comes from ? I didn't find anything), but I've got
everything I want : all syslog logs are forwarded and also the screenlog.0 file.
What do you think ?
