# This is here because otherwise when nginx starts at boot, the IPv6
# interface is marked as "tentative" until it finishes initializing,
# which will cause Nginx to bomb with this error:
#
# nginx: [emerg] bind() to [2600:3c02:e000:d::104]:443 failed (99: Cannot assign requested address)
#
# Ooops!
#
# So what we're going to do instead is wait until the IPv6 interfaces
# finish coming up.
#
