New Revision: 245525
URL: http://svnweb.freebsd.org/changeset/base/245525
Log:
Add a conditional sleep 1 in case we add any IPv6 addresses to interfaces.
Do this per jail started, not per address. This will allow DAD to complete
and services to properly start. Before we have seen problems with services
trying to start before the IPv6 address was available to use and thus
erroring and failing to start.
MFC after: 3 days
Reviewed by: simon
Reported by: clusterad
Seen before by: myself (but never fixed it properly)
Samples of services seen starting up really fast and failing included
openldap's slapd and I think even apache.

Bjoern A. Zeeb You have to have visions!
Stop bit received. Insert coin for new address family.
