Jeremy, All,
On 2014-06-17 13:21 +0800, Jeremy Kerr spake thusly:
> The (u)dhcpc hook installed by the busybox package configures the
> network and exits. If we want to do anything further with a DHCP lease,
> we'd have to replace the script entirely.
>
> This change introduces a .d directory for hooks (based on the script
> filename), which are executed after the interface configuration. This
> allows packages to drop a script file in the .d directory to perform
> actions on DHCP events.
>
> We'll use this in a later change to notify petitboot of DHCP boot
> information.
