Subject: start: use lxc_raw_clone_cb() where possible
X-Git-Tag: lxc-3.0.0.beta1~94^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ac2ba69621f0529b163d3a86772ace9d6601c21a;p=thirdparty%2Flxc.git

start: use lxc_raw_clone_cb() where possible

This way we can rely on the kernel's copy-on-write support similar to fork().
