Subject: Clarify the template-specific options a bit in lxc-create's help
X-Git-Tag: lxc-0.7.5~23
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c3ab01ffd3f59786fef85a5cbb1718659630f4d;p=thirdparty%2Flxc.git

Clarify the template-specific options a bit in lxc-create's help

This does not supplant the need for a manpage, but it's a start.
