Subject: display an explicit warning when netlink headers are missing
X-Git-Tag: lxc_0_6_3~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c8c9ce7a2b5bc4bf2615d83d71614829f36e51c4;p=thirdparty%2Flxc.git

display an explicit warning when netlink headers are missing

"netlink headers not found" implicitely means we have to install the
kernel headers. Make this explicit.
