Since a baselayout update Apache fails to start on Gentoo at (re-)boot of a server if that server has unused ethernet interfaces.
The symptom is that Apache fails to start on boot although it has been added to the runlevel with
rc-update add apache default
This is caused by recent baselayouts not working properly with more than one eth and not all of them being up.
Thus changing depend() { need net ... } into
depend() { need net.eth0 ... } at the top of /etc/init.d/apache2 will help.
While you're at it you could also add an nice after urandom to the existing depend () construct
and make sure apr and apache are emerged with flag urandom set. Reading from /dev/random to initialize the digest authentication mechanism (or SSL for that matter) might cause apache to block otherwise if there is not enough entropy in the random pool.
