That explains the at-boot v/s after-restart behavior...
Can be started later, based on a sysvinit "stage" like "$network", etc.
Does ipv6 come up cleanly if you do a soft or hard restart of apache
in rc.local?

All that you really need for ipv6 is the "::1 ..." line. Having one
line less on your X-less box won't make a difference.
Is this your entire "/etc/hosts"? Don;t you have any ipv4 settings?!
