Patch of this fix
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. Fixed in upstream commit c145e81. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: We found that there is a possible logical error in the following section in rc.sysinit: ipaddr= if [ "$HOSTNAME" = "localhost" -o "$HOSTNAME" = "localhost.localdomain" ]; then ipaddr=$(ip addr show to 0.0.0.0/0 scope global | awk '/[[:space:]]inet / { print gensub("/.*","","g",$2) }') for ip in $ipaddr ; do HOSTNAME= eval $(ipcalc -h $ipaddr 2>/dev/null) [ -n "$HOSTNAME" ] && { hostname ${HOSTNAME} ; break; } done fi The "for ip in $ipaddr ; do" loop seems to eval the hostname each of the IP address obtained above and then set the hostname. But it seems that: eval $(ipcalc -h $ipaddr 2>/dev/null) should be changed to: eval $(ipcalc -h $ip 2>/dev/null) Because if $ipaddr have multiple IP address, ipcalc would not work properly. Version-Release number of selected component (if applicable): initscripts-9.03.17-1.el6.x86_64 How reproducible: Always Steps to Reproduce: Actually I don't know how to setup IP address in such early stage of boot. May be using kernel parameter? It need to setup more then 1 ip address to reproduce the problem. Actual results: hostname properly set Expected results: hostname not set and remain to be localhost
