Package: ifupdown
Tags: patch
Attached is a patch providing an option to keep the lease. A new
optional parameter is created in the /etc/network/interfaces file. The
default is set so the current behavior is not changed, thus there is no
impact on existing systems.
Please apply this patch to ifupdown.
