Created attachment 407556 [details, diff] qmail eclass ifconfig patch qmail.eclass calls /sbin/ifconfig instead of /bin/ifconfig
Comment on attachment 407556 [details, diff] qmail eclass ifconfig patch that does use the new path, but the code is still broken. it's expecting the old ifconfig output which hasn't existed in a long time and thus would produce garbage tcpconfig rules.
should be fixed with this rewrite: http://sources.gentoo.org/eclass/qmail.eclass?r1=1.9&r2=1.10
