Subject: unshare the utsname in all the cases
X-Git-Tag: lxc_0_6_3~41
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1ea6db2923761b45b4400c32810b17f58785057a;p=thirdparty%2Flxc.git

unshare the utsname in all the cases

The current code implies we have to define a utsname in order
to unshare it. This problematic in case of system container because
we want them to set their hostname. As the utsname namespace is
a COW, we can safely unshare it in all the cases.
