Subject: conf: warn when capabilities are disabled or libcap is not found
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d8fd27b57bf1ebc9cdbf129547961339dd45b8b;p=thirdparty%2Flxc.git

conf: warn when capabilities are disabled or libcap is not found

The reason for this warning, is that the project will compile and when it does
not work, it's not clear from the logs what the reason might be.
