Subject: Re: Dracut help
Here we are, 10 days later, and I found it. DHCP of all things. When I
changed the default lease time on the DHCP server, the freeze time
changed, "coincidentally" to the same value as the lease. Then I found
a Red Hat bug report
(https://bugzilla.redhat.com/show_bug.cgi?id=1256042) with the same
issue and the end result is "it's by design." Ugh. So I changed the
default lease time to a week - now no problems.

Regards,

George Toft
