The commit
commit 7d69a1f4a72b18876c99c697692b78339d491568 Author: Cedric Le Goater <clg@fr.ibm.com> Date: Sun Jul 15 23:40:58 2007 -0700
remove CONFIG_UTS_NS and CONFIG_IPC_NS
accidentally removed the code, that prevented the uts->hostname and uts->domainname values from being overwritten from another namespace. In other words, setting hostname/domainname via sysfs (echo xxx > /proc/sys/kernel/(host|domain)name) cased the new value to be set in init UTS namespace only.
Return the isolation back.
